I have a friend who loves ripping on fat chicks with attitudes. I think it genuinely shocks him that they can actually have such egos, and he used to take delight in knocking them down a few pegs. Note that he would never instigate this, he'd only respond to attitude he was given.
A great exchange...
Fat chick: No offense, but you just strike me as a real douchebag. My friend deserves better
My friend: I'm sorry to hear you say that. You seem like you have your stuff together though. I can tell you've lived a full and rich life
Fat chick: Really?
My friend: Yep, FULL of RICH, gooey toppings...chocolate, butterscotch, what-have-you, drizzled onto mountains of ice cream and covered with heaping handfuls of candy bits.
Fat chick: Fuck you!
My friend: Tell me, what is the most indulgent, decadent treat you've ever inhaled?
Fat chick: FUCK YOU!!
My friend: I'm sorry, I'm being a real asshole. It's been a hard month for me on a personal level. Let me make it up to you.
Fat chick: How?
My friend: If you calm down, I promise to deposit a #6 Combo from Wendy's on your doorstep, no questions asked.
