Po-po-po-po-zao. Po-po-po-po-zao.

Kevin Federline dropped by Ryan Seacrest’s radio show on Thursday morning to promote his new single, the infamous PopoZao. Which recently learned is slang for “big butt.” Charming. K-Fed was reportedly jamming to some Brazilian music when he brainstormed the name of track. Hey, at least he didn’t claim that this was inspired by Britney.
