It's an apt title.
The minute-long clip shows Lopez and a few dancers twerking in a vacant lot. On paper, that's it, but this is Jennifer "Fly Girl" Lopez. This is not some new-to-the-twerking-game rookie. This is how it's done. We hope you're ready.
Also, PSA: Lopez is 44. If that doesn't make her performance in this video more impressive, we don't know what will.
