It's a harsh, insulting way to tell someone to shut up, mostly used in online arguments and TikTok comments. Some people use it jokingly with friends, but it's rude and best left out of your own posts. - [TikTok challenge](https://postmesh.app/glossary/tiktok-challenge): A TikTok challenge is a trend where people film themselves doing the same dance, task or prompt, usually with a shared sound or hashtag, and invite others to try it. Most are harmless fun, but TikTok's rules ban challenges that risk serious injury. - [TL;DR](https://postmesh.app/glossary/tldr): TL;DR stands for too long; didn't read. People use it two ways: as a blunt reply saying a post was too long to bother with, and, more often today, as a label for a one-line summary of a longer post, as in "TL;DR: the meeting moved to Friday." - [TMI](https://postmesh.app/glossary/tmi): TMI stands for too much information. People say it when someone shares a personal detail they'd rather not have heard, and they say it about themselves as a warning that an overshare is coming.
