when the hos, tricks, or scallywags exhibit their truest quality of being a total biatch and simultaneously a straight up ass.

The combination of the words bitch and ass. Bitchassness is a word that means some one is acting like a bitch and a jackass. When some one does some thing juss to piss another person off just to do it this is called bitchassness.
You see your friends BFtlking or looking at another girl knowing that he doesnt want her at all... so you call your friend so that she can show up and see this and think the wrong thing.... That is an act of bitchassness
