A guy who is only fun when he is drunk. Otherwise he is pretty boring when he is completely sober. Often a reference to an episode of the sitcom Friends where Monica dated fun Bobby, who was not only boring, but downright depressing when sober.
I just hope this new guy I'm dating isn't a fun Bobby.
