An app for Android/iOS devices that lets you lip sync with a song of your choice. While the app is intended for everyone to have fun, it's sadly used the majority of the time by pre-teens, divided between annyoing fuckboys and little girls dressing like they are on a date with Pedobear, thus making it a subject of cringe.

Get the musical.ly mug.
A pointless app that 11 year olds that have no talent are obsessed with. You lip-sync to songs and people follow you for it.
"Musical.ly still exists?"
"Yeah. My 11 year old sister and her friends use it. It's so annoying."
