Hmm, that's tricky as it would require a non-personal idea of "horrible". If I found it horrible I wouldn't want to be friends. But I suppose I can tolerate all sorts of things as long as they are fun to be around more often than not.
Peer pressure I might tolerate if they pressure me to try something that I actually enjoy, not so much if they pressure me into something I hate. But I've often been pressured into things I ended up enjoying, like cobra liquor, which my friend pressured me to try only for me to like it and he was like, "What? Huh? Lemme try that!" (then he found it gross and spit it out, but I actually liked it).
And a person can be incredibly stupid yet fun to be around. I don't even see stupidity as a negative quality as far as having a good time with friends (sometimes I really enjoy the slow ones).
Gossiping is probably the worst one I can't tolerate very well. I steer clear of gossipers, as they wield words like poison to smear people, and I would never want to stoop to their level, but they don't fight clean and honorably... so best to avoid them as I see it. If there's one personality trait I dislike most, it's the gossiping and backstabbing kind.
