Prabtard
Def: Leeds (UK) slang for "retard". A person of severely reduced mental ability. Derrivations function much like those of retard; i.e. "prabtarded" and "prabtardedness" are a correct adjective and slang noun respectively.
That girl is such a prabtard. I cant believe they let her out of the house.

Have you seen the video on youtube with the prabtarded horse? Its bare jokes.
