I was in the process of looking up the name of the OMG awful movie someone showed at a sex party once (yes, a sex party) that involved zombies and teenagers at a religious camp, and porn, and ... and then I remembered why I had tried SO HARD to forget it, mainly the awful songs in it, and so before I do remember that I'm stopping, but you should totally go find it. I expect you'll realize it when you do.

BTW, in googling 'movie zombies camp porn' there were links to a gay zombie porn movie that was banned in australia somewhere. That might be amusing enough to watch...
