I've never seen the show, I've only heard about it... but I've unfortunately hung out with Fabian a few times because my friend was going out with him for a while; and I can sincerely say that he's the biggest, fattest jerk in the world.
In the world. The guy has no shame-- when he was going out with my friend, he used to hit on me and a couple of other friends of ours... and not in a joking way. Besides, he's so stuck up it's not even funny.
If you ever get a chance to kick him in the face, please do.
