Afrikaans in origin - poes (vagina) and klap (slap). Pronounced "poosklup" with long "oo". Rhymes with goosecup if that was actually a word. It is the type of slap administered to a recipients head in such a way that their eyes bug out, their sphincters let go and their descendants end up sporting black eyes and stunted mental development.
