In an obviously misguided attempt at mocking the playoff structure of the NCAA tournament, we’re inviting readers to enjoy matchups of actual fetishes in a voter-powered tournament, culminating in April with the Nasty Fetish Final Four. That tournament continues today with Regional Semifinal action. Remember, you’re voting for what you consider the more nasty fetish.

1. Necrobestiality

Literal Meaning: “When a gentleman engages in sexual congress with a corpse of a departed animal friend.”

The Intarwebs say: Also good for the beasts themselves.

Notable Advocates: Tony Siragusa, Chris Tucker, Peggy Noonan

13. Incest

Literal Meaning: “Any sexual activity between closely related persons and (often within the immediate family) that is illegal or socially taboo. Prevalence is difficult to generalize, but research has estimated 10-15% of the general population as having at least one incest experience, with less than 2% involving intercourse or attempted intercourse.”

Wiki says: “Having an incest fetish is all down to how you feel.” Are you feeling particularly incesty today?

Notable Advocates: Jason Witten, Jeff Bridges, Yo-Yo Ma
