Name given to a usually male masturbator who utilizes discarded dirty female underwear pulled down over his face like a super hero mask to savor scent, but also to keep his hands free for strenuous self abuse.

Instead of being a super hero fighting crime - he’s more of a super weirdo fetishist “fighting” himself
My wife left some creamy musky underwear discarded on the bathroom floor - the thonged avenger made an impromptu appearance.

Get the Thonged Avenger mug.
A Web Comic that was created in 2010 to make fun of an actual person who put on a thong to freak out a friend's mom.
In the Web Comic Zeff uses a thong of power to fight crime. He is the worse crime fighter in the history of crime-fighting for obvious reasons. And in love, he is always rejected.

The website did not support itself and was taken a few years later.
I wanted to be a strangely perverted superhero like The Thonged Avenger.
