I can't think of anything witty to say to him that doesn't make me sound like a huuuuge douche. I don't want to come in and start stuff by being like "Oh happy birthday, by the way most of the school told me they hate you when we where talking a while ago, we should catch up!"
but I want something that will make him upset and sad.
Anyways for the moralcigarettes that care he deserves it, the first time I spoke to him we where grouped together with 2 other people, I was like "Yo Dylan pass the bunson burner" and he was like "Shut the forget up and get it yourself friend" This was only the first time we spoke but he's been a douche ever since and pretty much the whole school including his best friend who is one of my best friends.
TL;DR: I need ways to zing an starfish on his birthday.
