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.
Person 1 : Have you seen the app musical.ly?
Person 2 : Yeah, it made me lose faith in humanity.
