Acne on a butt, usually on the phat ass of a girl who would be good looking if it weren't for the horrible acne on her face which we all know is not limited to her face. An acne breakout on the butt that is so bad, the bitch needs to say fuck proactive and become reactive
Nicole's ass is so fine but you know it's covered in Bucne, look at her face!!!
