Mutuals are people who follow each other on social media: you follow them and they follow you back. "We have mutuals" can also mean you share friends or followers with someone, even if you don't follow each other.

## What mutuals means

A mutual is someone you follow who also follows you. Merriam-Webster lists the noun as informal and defines it as a reciprocal follower on social media. So when someone says "we're mutuals," they mean the follow goes both ways. When they say "you're one of my mutuals," they're counting you among those people.

There's a second sense that comes from mutual friend. Cambridge Dictionary gives both: a mutual can be a person who is a friend of two people, or a mutual follower on social media. That's why "we have mutuals" usually means you share connections. You might not follow each other at all, but some of the same people follow you both.

The tone is friendly. Being mutuals implies at least a little interest in each other, more than a one-way follow. It doesn't mean you're close. Plenty of mutuals have never exchanged a word, but it's a step up from stranger.

## Where mutuals comes from

The adjective mutual is old. Merriam-Webster traces it through Middle French mutuel to the Latin mutuus, and dates its first known use to the 15th century. For most of its life it described feelings or arrangements shared by two sides: mutual respect, mutual friends, a mutual agreement.

The social media noun is recent. Merriam-Webster dates the first known use of mutual meaning a reciprocal follower to 2008. The shorter, playful version moots has its own entry too, which Merriam-Webster marks as informal and points straight back to mutual.

- 15th century: First known use of the adjective mutual, from Latin mutuus (Merriam-Webster)
- 2008: First known use of the noun mutual for a reciprocal follower on social media (Merriam-Webster)
- December 2022: Instagram launches Notes, shared with followers you follow back or your Close Friends list

## How people use mutuals on social media

On X and Tumblr, mutuals are a social group of their own. People talk about "my mutuals" the way you'd talk about coworkers or classmates: a crowd you see every day and know well from their posts. You'll see posts asking for more mutuals in a niche, or thanking mutuals for support. Moots is the affectionate shorthand.

Niche communities lean on mutuals hardest. In fandoms, art circles and hobby spaces, your mutuals are often the people who share your work, answer your questions and show up in your replies. Losing a few can feel like losing a group of friends, which is why you'll see posts announcing a new account and asking mutuals to follow it over.

On Instagram, "we have mutuals" is the more common use. It's how people place a stranger: if you share followers, the person probably isn't a bot and might be from your school, city or friend group. On TikTok, the term is less needed because the app does some of the sorting for you, as the next section explains.

- "wait we've been mutuals for two years and never talked??"
- "looking for mutuals who are into film photography"
- "mutuals only, don't come for me"
- "we have like 40 mutuals, how have we never met"
- "love my moots, this app would be unbearable without you"
- "just realized my favorite artist is my mutual and I'm being so normal about it"

## How apps treat mutuals

Some apps use the follow-back relationship to decide who sees what. TikTok's Friends tab shows posts from followers you follow back, which TikTok calls your friends, plus accounts you follow and suggested accounts, according to its help center. In other words, TikTok's friends are your mutuals.

Instagram uses the same idea for [Instagram Notes](/glossary/instagram-notes). When Instagram announced Notes in December 2022, it said you could share a note with followers you follow back or with people on your [Close Friends](/glossary/close-friends) list. Mutuals get a quieter, more personal channel than your full follower list.

That's one practical reason mutuals matter beyond bragging rights. On those surfaces, being mutuals is the ticket in.

It also explains why a follow back can feel like a bigger deal than a like. Once you're mutuals, you may start seeing each other in places that aren't public to everyone, and the other person may see more of you. If you'd rather keep someone at a distance, you can let them follow you without following back, and they stay a follower rather than a mutual.

## How to check who your mutuals are

The quick way is to compare your Followers and Following lists, but that gets tedious past a few dozen accounts. Our guide on [who doesn't follow you back on Instagram](/blog/who-doesnt-follow-you-back-on-instagram) explains how to find one-way follows, which is the same question from the other side.

Before you unfollow anyone who isn't a mutual, think about why you followed them. Plenty of accounts worth following, like news outlets, artists and brands, will never follow you back, and that's fine. Mutuals are about people, not a score. A short list of mutuals you actually talk to is worth more than a long one you never see.

## How to reply when someone wants to be mutuals

If someone asks "mutuals?" or follows you and says hi, you're free to follow back or not. A follow back is the simplest yes. If their account seems spammy or you don't want to share your posts with them, ignoring the request is normal and doesn't need an explanation.

**Someone asked to be mutuals. What do you do?**
- You like their posts and they seem real → Follow back. Saying hi in a reply or DM is a nice bonus.
- You're not sure who they are → Check their profile and whether you have mutuals in common before deciding.
- It looks like spam or follow-for-follow → Ignore it. You don't owe anyone a follow back.

If you're the one asking, make it about something specific: a post you liked, a shared interest, a mutual friend. "Mutuals?" with nothing else reads like a numbers game.

### When a mutual unfollows you

It happens, and it's rarely personal. People prune their feeds, change interests, take breaks or start fresh accounts. Before you read meaning into it, check whether they deactivated or switched to a new handle. If it was someone you actually talk to and it bothers you, a friendly message is fine. If not, letting it go is the low-drama choice.

Avoid unfollowing back the moment you notice. Tit-for-tat unfollows tend to get noticed in friend groups, and they can turn a tidy-up on someone else's part into a small feud. If you'd still enjoy their posts, keep following.

## When not to use it

For brand accounts, chasing mutuals is usually a trap. Follow-for-follow schemes inflate your numbers with accounts that don't care about what you sell, which can drag down your [engagement rate](/glossary/engagement-rate) and make your audience harder to read. Follow people you actually want to hear from, and let customers follow you.

In professional settings, mutuals can be fine as a word, but on LinkedIn people talk about connections instead, so use that there. And remember that "mutuals only" isn't a privacy setting on most apps. If a post needs to stay within a small circle, use the app's actual tools, such as Close Friends on Instagram, rather than a polite request in the caption.

## Mutuals vs moots, oomfs and followers

**Follower**
- Follows you
- You may not follow back

**Mutual**

**OOMF**

| Term | What it means |
| --- | --- |
| Mutual, mutuals | Someone who follows you and whom you follow back |
| Moot, moots | Informal short form of mutual |
| Mutual friend | A person who is friends with two people |
| We have mutuals | We share friends or followers |
| Mutuals only | A request that only mutuals engage, not a setting |

[OOMF](/glossary/oomf), one of my followers, is the closest cousin. Your oomf is someone who follows you, and they might be a mutual, but the word is used to talk about one person without naming them. If you want to understand why a stranger's post suddenly fills your feed even though you aren't mutuals, that's the [algorithm](/glossary/algorithm) at work, not your follow list.

## Questions

### What does it mean to be mutuals?

You follow each other. Each of you follows the other's account.

### What does "we have mutuals" mean?

That you share connections, people who follow or are friends with both of you. You don't have to follow each other for this to be true.

### What are moots?

An informal short form of mutuals. Merriam-Webster lists it as a slang synonym.

### Is a mutual the same as a friend?

Not always. Mutuals follow each other, but they may never have talked. TikTok does call followers you follow back your friends, which is why its Friends tab is really a mutuals feed.

### What does "mutuals only" mean in a caption?

The poster wants only people they follow back to reply or share. It's a request, not a privacy control, so anyone who can see the post still can.

### How do I see my mutuals on Instagram?

Compare your Followers and Following lists, or look for accounts you follow that also appear among your followers. Our guide to who doesn't follow you back covers the reverse.
