Rigby has all the fearlessness and shamelessness that come with complete immaturity. He's like an out-of-control teenager, with no boundaries whatsoever.
Mordecai is a young blue jay with a burgeoning sense of responsibility, decency, and his own mortality. But that doesn't mean he doesn't like to have a little fun every once in a while--stupid fun.
