The word 'funk' has been a little transitional in the last few years, because I'm pretty sure that most people wouldn't want the sex they're having to be 'funky' - especially in the smell department. Regardless, Torrent Funk is an archive of peer to peer files that you can get your hands on with a selected category devoted just to adult entertainment.
The torrents are listed in a bunch of different ways with the potential to sort by all uploads, those recently added and the torrents that have been verified by the admins. Looking through the content, it looks as if Indian porn is a big selling point here: the top 5 scenes all feature Desi girls doing nasty things in front of the camera.
You'll also find stuff like The Fappening, Fifty Shades of Grey DVD Rips, professional paysite releases (Bang Bus, Money Talks, etc.) and other adult content. It also has a mainstream area for non-adult torrents and with its current archive sitting at 8 million torrents, it's pretty good in terms of size too.
