NSFW?
There's no nudity just so you know, although there's some implied sex jokes and swearing. It's definitely one of the stranger things I've seen on the internet.
Thanks Shelby for the link.

Update: Here's an episode of The Cinema Snob that explains a bit about the origin, and for that matter covers a mildly SFW synopsis of it's sister "film" "Super Hornio Bros"
The whole movie company specifically does art snuff films and porn apparently.
