First glance/sight/blind date and/or internet turn offs

[Lasonja]

I searched on this, and I did see quite a few threads about this topic. Most of them had me ctfu, but this one is different. The other threads had a long laundry list of different turn offs. In this thread we post only one turn off. I'm not talking about turn offs you get when you talk to the person. Ex: "If he/she is not religious" "bad breath" etc. I'm talking more on the lines of when you first see someone, you might find that person attractive from the start, but there's one thing that stands out about that person that's so much of a turn off that you would not give that person the time of day. Or if it's a blind date, or someone you met on the internet, when you finally meet them in person, what would be the ONE (only one) turn off that would make you say, this is the first and last date etc?

Mine would be a man who wears really tight jeans. I don't care what his body looks like, how fine he is, if he's wearing tight jeans, owns a pair of tight jeans, "hayle to the naw", he has no chance.

You?

ETA: And nothing like "he/she stinks" because you have to be up on that person to smell them. This is first sight/one sight only.
