Crunk refers to the net effect of excessive partying with marijuana and alcohol. It is also used to mean a state of inebriation without regard to the delivery vehicle.
Yeah, that was Conan's joke "every time on the smurfs, they would always say "smurf" like every other word.. so on this show, we're inventing our own word.. in case guests need to feel the need to curse. We call it: KRUNK. (man shows sign with KRUNK on it). KRUNK. Andy?"
