arrogance. not to be confused with confidence. confidence is good, but arrogance pisses me off. i hate people who have a misplaced sense of superiority. chillax >.

Arrogance is certainly a turn off. I also think that if the person isn't very smart and especially if he has a "dumb" expression on his face (you know the blank stare and the open mouth), it's game over for me...

but sometimes people can LOOK st00pid and be actually quite smart... lol.

So many things (no wonder I'm a virgin).

Teeth: Lots of problems here. Big teeth, small teeth, narrow teeth, wide teeth, long teeth, short teeth, gaps, over bites, underbites, cavities, fillings, caps, gold teeth, yellow teeth, stained teeth, gums that aren't the color red, lips that are too big, lips that are too small, people who don't floss, people who floss too much, missing teeth, too many teeth, plaque, tartar, good lord too many to name.

Other things include blemishes on skin, under confidence, over confidence, lack of boobs, too much boob, fingernails too long, big hands, small hands, fingernails too short, fingernails not manicured, dry hands, and that's all off of the top of my head.

Haven't met one yet. It would still be a turn-off for me though ...
