How do you put up with a brother who never lets go of an opportunity to deride you, undermine your self-worth, and make you regret he was your brother?

I feel so ashamed for having brought him into the house, (I introduced him to the house and rushed him). I've never been a morally exemplary member of the house, being the definative party animal on campus. But the level of rudeness he can display without so much as a flich makes me stand there dumbfounded.

I'm not here to whine to you guys. I really wanna hear of similar experiences and how they've been dealt with.
