term used to describe carelessly doggystyling the shit out of someone and your wanker slams right into an ass cheek about breaking your rock hard cock in half...after which you remain in the fetal postion, crying like a little girl for hours
While railing the hell out of some chick last night, I ass crunched my cock and I can't even fucking walk!
