Where a chick has an ass so big you can see it from the front. Ass so big they wrote a song about it. So big you can put a tea cup on and not spill it. Not those nasty cottage chez sagy ass but something round and bootylishis!
That chick that walks down the street and everyone knows here from her booty. Padunkadunk.
