What is your biggest turn-off for a guy or a girl?

I think Hygene is a big one for sure. I don't like smelly or dirty guys or the king of guys who will not wash their clothes often or even if they are just un-tidy in the house because if we end up together I would have to live in that mess.

i would have to say being a snob or bragging about themself and as well thinking they are better then you and everyone else

Well, one of the things that turns me off is when a girl won't stop talking about her previous boyfriend. I met this girl and she was hot and had a great personality. We started talking and all she talked about was her ex boyfriend and it got so annoying. Another thing that turns me off is if a girl is too loud.

I find it off if the picks his nose in public. That should be done in private. It is totally gross if someone, a guy or a girl does that in public. It is totally off.

well, the biggest turn off would be bad breathe and bad odor :( i hate foul smells and i can't bear them, so a girl if wants to talk to me should check her underarms and her breathe as well, may be use a mouth fresh but these two are the biggest turn offs for me.
