Brendan: So where were you last night? You left the bar pretty early.
Edwin: Yeah I know, I met these two sorority girls last night and I ended up going back to their house and had a threesome.
Brendan: Sick dick!
Edwin: No, even better. Turns out we were being super loud while I was giving them both an alabama hot pocket and I woke up one of their other sisters. I guess they're really comfortable with each other because I ended up giving the third girl a birmingham booty call.
Brendan: You're right, thats Cock Diesel!
