Frank: Yo Jimmy, wanna get eats?
Jimmy: Gee Willikers! I would love to tag along, but first let me change my clothes.
Jimmy: You see Frank, I like to wear tight clothing because it makes me look big. Don't tell anyone, but it's really just an optical illusion.
Frank: Jimmy you're absolutely right, go ahead and change. I'd rather look like a douchebag than a pussy, too!
Dave: Oh, you guys are leaving for the Pub? I'll go with you.
Frank: Ummmm, did either of us invite you Dave?
Dave: Do I have to be invited to go out to eat?
Frank: Hey Dave, how about you answer my fucking question before you bring up another one. You gotta listen Dave...pay fucking attention to the words that come out of my mouth!
Dave: ...I wasn't invited.......fuck you Frank! You're always such a dick to me, and I never do anything to deserve it.
Frank: Actually Dave, I'm just keeping it real. When you fucking come at me, spitting fucking inquiries in my face, I'm not gonna back down.
Dave: You know what, fuck this! I don't even want to argue with you anymore.
Frank: Fucking t-wift bitch, walk away!
