I thought of some...
"I saaaaw you rollin' your eyes at me HEFFA!" I guess this would be a variation of "you look mean".
When I see old friends, "Have you graduated, YET?" Come on, five years in undergrad isn't THAT long!
"Oh my, you have a deep voice! Do you sing?" It's not that deep, I don't sound like a man or anything.
"You have to be 21 to do _____" Yes, I do look 16, don't be jealous!
"Girl, is you mixed wit Indian?" No comment.
"Can I have some of your _____?" NO! It's MINE! Get your your own damn _____! Yes, I'm spoiled like that. Sharing sucks! Don't be hating because I only gave you only one french fry or nacho chip. That's what some peeps get for gambling up all of their money.
"You are soooooo cheap!" No, it's just that I don't have that much money. Also, I'm sorry, but i'm above paying (extra) for certain stuff.
