Smoking is a big one. It's horrible and makes you stink.
My other main one is piercings. I can't stand the things. Earrings maybe, but facial and body piercings just look awful.
THIS! Thank you! I get it, stabbing bits of metal into your face makes a statement you like to break the mold, but it makes you look creepy, and gives me the slight temptation to follow you around with a magnet!
Also, nose picking. Yes, it's some people's habit, but use a tissue, and certainly don't do it when you're trying to be sexy! (Never been an issue with girlfriends, but I was watching a porn webcam once (shut up) and this woman just picked her nose in that very slight way that's like "oh, I'm trying to be subtle and failing" for about thirty seconds. So yeah, I was gone.)
Oh, and people that just cake on the make up, I just want to scrape a spade along their cheek to see how much foundation comes off.
