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.

" Nah man, she showed me the videos she made on Musical.ly.

The app where little kids and vines stars go to show that they have no talent. Almost none of it has real music just 12 year olds doing voice overs of terrible vines. There is rarely talent and when there is they don't get the credit they deserve.
