Notes

“Yes, but at least my stink will shower off, unlike your rancid personality." if they say you're not worth their time to insult, reply "Well, I'm glad to hear you weren't actually trying to insult me the past five minutes." "Oh, that last insult was so close to making sense. Please keep trying." "I'll come back when your tantrum is over so we can get back to trading insults."
"You and I have so much in common at times, don't we?" Use this for an insult about your weight, appearance, intelligence, etc. "Yes, I used to have that same problem in school ... preschool, that is"
“If you had a brain you’d take it out and play with it.”
“I’d love to give you a nasty look, but it appears you already have one.”
how did you get here? did someone leave your cage open? "Why are you crying/looking so sad? Is it because of your hair?" "You know I don't mind that you're not smart. Or pretty. What I do mind is that your parents are brother and sister." "If you ate some of that makeup, you would be pretty on the inside too." "If she ever meets you, even Hello Kitty would say goodbye." "You know, I know three fat people and you're two of them." "If you're going to be two-faced, at least make one of them pretty."
