Hahahaha. I know you didn't mean it this way, but what I read in your comment was: disgusting = YAY! ;D I wondered if anyone else had friends who were squicked by the pairing. I know I had friends in fandom, some of whom had known me for years if not decades, who were horrified to find I was reading Snarry.
I also found HP fan fic before properly becoming a HP fan. I think I was reading HP fan fic for 8 months before I opened the first HP book. Though I had seen the first movie so was somewhat familiar with the characters even though I thought Remus Lupin had to be an original character the first time I came across him in fan fic.
I can't remember the name, it was a short one where Snape made Harry lick his own, erm, happy ending off a mirror.
Oh, noes! Now I am going to be searching for that fic all day because I know I read it. True, there may be more than one, but that sounds so familiar....Ah, such a hardship to go searching through all those Snarries. ;D
