Severus Snape (born January 9, 1960) is a really extremely gay wizard at Hogwarts. He is also a pedophile and he lusts about his butt buddy Harry Potter's tight ass. He also enjoys BDSM stuff, and is known to be a gay sex potion maker.
He didn't actually die. He only faked his death to escape Hogwarts so he can join the Barney Bunch.
