Smoking is quite ick. I also don't like excessive drinking, drugs, stupidity, ignorance, lack of creativity, complete disregard for music and/or video games, lack of physicality (meow), illogic (unless it's funny), no sense of humor, too much immaturity, emos, punks, goths, college bitches, muscley women, too superficial (of course, I'd never get to be with anybody superficial anyway).... there are probably more, but I can't think of them. Sorry I couldn't put only one or two... I just don't care to compromise much on these things.
