That was a joke between friends Spydie, and the come back was takeing it. That's how some friendships work. Sertain people don't understand that, but they have to realize, that the person who says them dose not intend to hurt them at all, and it is just mearly a joke, and how MotD replied is useally how it is taken (or if they can't think of anything, then they laugh and say 'bitch', to announce there defeat)
MotD: Laughing lol, bitch! Razz
