An acronym formed from a mix of other most powerful curse words. Used when there is no better way to describe the disgustingness of a person; the worst kind of person possible. Also used as a "cover all" when one cannot think of words to characterize someone who is absolute "dirt". Can be used to describe a person of any sex.Onanist
