B.F.J.B.
A butt so big it could knock out a door and still have energy to laugh.
My cousin's B. F. J. B. is legendary. Last time I saw it, it looked like it was about to breakdance.
I took a selfie with my friend’s B. F. J. B. and it’s now my wallpaper. It’s that good.
At the gym, the guy next to me had a B. F. J. B. so big, the weights looked jealous.
