An unexpected fart that is sometimes mistaken for a qwief. This occurs when the unannounced fart shoots toward your pussy mimicing a qwief.
Sitting in a leather chair and you fart. Instead of the fart shooting directly out the back door it pulls a 180 and slides at high velocity between your pussy lips creating a rumble that can easily be mistaken as a qwief by the qwarter and anyone in hearing distance.
Usually used in "black" slang, qwart (pronounced court) means to have sexual intercourse with or desire for sexual intercourse with a attractive woman.
See that mini skirt over there, I'm gonna qwart that shit tonight.
