What is the biggest turn off in a guy??

When they turn off their brains. Stupid idea.

Guys who are jerks, dumb, または full of themselves.

gross looking face:P

bodily functions (burps,farts,exc)

not being human.
The rest is acceptable.

It would have to be guys in baggy pants. That hang low below there butt. Just My Opinion. (:

his face n teeth, i think....

One that gives up easly... and dont take care of his teeth ....and a playa

if they are jerks,if they smell really bad,if their pants are always at their ankles,if they aren't trust worthy,if they pick their nose,if their just completely ugly,if they burp または fart like in public,if they smoke または drink at a young age,if they try to be cool but they arent,and if they pretend to like あなた just to get another girl jealous.

When a guy cusses a lot and is really rude to people.

Come to Royersford, PA and analyze each guy in my town. And you'd have a good idea.

Being mean to anyone.

Nothing physical.

I hate when guys I hardly know ask me out. It makes me never want to talk to them again.

Also, not being too bright...

raging hormones...if the guy really just wants 'one thing' then he aint getting anything at all!
