They got to talking, rather loudly, about swear words as one of them had apparently gotten in trouble for cursing in class.
Anyway, this part made me chuckle a little:
Girl 1: "What's wrong with saying 'ass'?"
Girl 2: "I know. Really!"
Girl 1: "It's not like I meant it like a butt or something."
Girl 2: "Didn't Jesus have an ass?"
Girl 1: "Yeah, he did! He rode a donkey! If Jesus can say 'ass' I can too."
