Negated Compliments

I was reading a blog entry of youngcel's about what I consider to be "negated compliments". These are not quite compliments, in fact they're usually offensive like when someone says You're cute to be dark, fat, short etc...My people I think it is common knowledge that such comments are offensive. Today for example, this young chap, about 17ish walked past me and said "You look nice today, I don't discriminate" at first it seemed like a compliment, I started to smile and say thank you when I heard the "I don't discriminate" part. WTF is that??? Like despite your flaws, I found something nice about you...Then awhile ago I went out with a few cousins when this guy (that is my cousin's friend with benefits)asked me if I wanted to get "nailed". I was like, who? damn! What? I'm not a charity case...He said "I know somebody named Peanut that would nail you" It took me half the night and a hint from his friend to figure out that he was talking about himslf. Or here's another one, when guys say things like, "I mess with big girls" i'm thinking, well I don't "mess" with ugly guys, damnit that is not a compliment. I have a friend that has been told her whole life that she has a pretty "face" and it's an inside joke that we call her "face" because people never just say that she's a pretty girl, because she's overweight, they always compliment her beautiful face.
People stop it, if you're gonna compliment somebody, just make sure you don't take it back by saying something stupid like...for a __________person.
