A few more to add:

Crack Smack: Any references, derogatory or otherwise to RT's "Broken @ss" or "Plumber's butt"

Black Smack: A type of smack where the ebonics dialect is mainly used. (Hey 'Yall used to be pretty good at this)

Pack Smack: When a whole group of board members gang up and smack down some trouble-making lurker.
