when a female's rear is so big, muscular, and round it resambles the hind quarters of a donkey or horse. Usually a good thing.
I coined this phrase in 1996. "Man, that chick's ass looks like a horse." "Yeah, She's got a donkey ass." I believe the hip-hop culture bastardized that prase tobedonkeydonk. I'll take credit for that.
