noun - The process in which a female removes a joint/blunt from the males mouth, inhales through her vagina, and quiffs out the smoke. The male then proceeds to eat her out, so they both get high.
Guy #1 - Yo, so I was smoking a J last night and my gf just takes it away and starts pussy kushing!
Guy #2 - Wow, what a waste of a joint!
Guy#1 - Oh, trust me, it wasn't ;)
