Have laughed so much at this thread tonight! Thanks for starting it.
I agree with most of these. Some of my additions are:
Being called 'Angel'.
Being asked for revealing photos of me, and the same guy phoning me for sexy conversation. I said I'd feel less cheap if he paid me.
I spent a year with a lovely guy ? he was so loving and attentive between the sheets - but he had a waterbed belly, bigger boobs than me and ED :( and in the end, they were dealbreakers for me.
A guy talking (in bed!) about his previous girlfriends is a big no-no: "I once slept with this girl who came 15 times in a session ..." Bloody great. Well, now I feel relaxed and ready to let go and climax! 
Uncontrolled burping.
Arrogance.
Bitten/dirty nails.
I feel bad saying this, but a guy with a tongue-tie. The kissing was a non-event, and that's before he ventured to other exciting parts of my anatomy, where the earth most definitely didn't (couldn't) move.
A man whose pants have skids in them.
A scarily close, blind loyalty/bond to his mother.
Shit English.
Manky feet.
A man massively, excitedly into his dog, cat, whatever other pet.
A man who thinks I should trim/wax my bits, who thinks my legs are bristly (when I shaved them that morning!) and is generally a controlling, perfectionist arsehole.
Amen.
