Casual Felon
A functioning drug addict. Someone who values a 48 hour straight, drug induced dance party over a clean criminal record. This person usually has a good job and and has never been busted for drugs, but doesn't understand that his weekend drug use is a felony because everyone he surrounds himself with is also indulging in an all weekend bender.
I just got to the party and the casual felons are still dancing in their clothes from two nights ago, high on coke and ecstasy.
