Twerking has been around for decades, but it's just now starting to make a name for itself in mainstream pop culture. The exploding dance style has been adapted by popular music artists, including Miley Cyrus and One Direction's Harry Styles, and has been featured in a wide range of YouTube videos, memes, and even movies and TV shows. Just this week, a new Miley Cyrus, Justin Bieber, and Lil Twist collaboration, called "Twerk," hit the Internet. But how do we know the twerking trend is here to stay?

Instead of including the definition, we're going to hand it over to Morgan Freeman, who read the definition of twerking while guest anchoring on Morning Express With Robin Meade. Take it away, Morgan!
