Musical.ly 

A really stupid app on both Apple and Android where people lip-sync to your fave songs for followers. Some of the so-called "celebrities" on Musical.ly get paid for what they do.

Musers come in 4 categories:

The shirtless boys who roll their bellies and bite their lips
The 14 year old girls who wear 4 pounds of makeup and lip-sync songs about pussy
The 9 year olds who need a script cuz they can't memorize things
The dancers

Some famous musers include:
BabyAriel
Jacob Sartorious
Loren Beech
Hunter Rowland
Almost every viner
Almost all the dance moms girls

Omg BabyAriel hit 5 million followers on Musical.ly yesterday!

An app to make your own lip-synched music video. Users are mainly attention seeking teenagers. While using the app, you will find yourself making idiotic hand gestures and you will look really stupid.
