Hey all, I doubt there's many hip hop fans here, and of the few that are I doubt they listen to or even ever have heard about Proof, but there's one song that lately just refuses to go out of my head.

The thing is, I can't make out the words in the background. It repeats in the chorus, but I have not found a single lyrics site via google that had the lyrics right.
Wondering if anyone knew what the hell is being said in the background. Sounds like "wopped up" or something?
