Good topic of discussion.

For me, my deal breakers would be:
-Smoking
-Drug taking/dealing
-Binge drinking
-Manipulative
-Selfish in bed
-Overbearing family/friends
-Still lives with said overbearing family
-No ambitions or drive to self-fufillment
-Doesn't like dogs or cats
-Insulting
-Lazy
-Lack of intellectual thought (I want to be able to have a smart conversation with someone)
-Misogynistic
-Sexist
-Racist
-Unemployed
-No sense of humor
-No sense of adventure
-Arrogance
-Mean to his mother
-Doesn't want children
-Doesn't want to get married
-Bad with children
-Constantly talks about ex-girlfriends/is in regular contact with exes
-Doesn't want to talk through problems
-Immature
-Jesus freak
-Homophobic
-Football thug
-Chaviness
I'm sure there's more but that's all I can think of for now.
I would probably be a good match, then.
