The condition when a man's underwear, usually briefs, have become so deteriorated on the back side that the material covering the ass cheeks has completely disintegrated leaving only the elastic band remaining. When exposed, the view from behind-to unwitting observers-appears like the wearer is sporting a thong.
Samantha: "I thought the plumber's crack was a nasty sight to witness. Yesterday, I saw a guy bend over at the gym revealing his man-thong."

A man thong is a male undergarment, typically worn by gay people. The front has a pouch to hold in your junk, and the back has a thin strap designed to look sexy! A thong is the second most sexy underwear behind the jock strap.
Look at his man thong, that is the sexiest underwear I have ever seen!

He is totally gay.

When a male acts in a manor which may be perceived as gay only because a women is not around. The affected individual acts as such do to high testosterone levels which make the male want to do gay things such as; whipping his balls out, humping, gay suggestive gestures(verbally), and for instance wearing Man Thongs amongst men.
Matt winked at a guy today.

Matt said he'd tap a guy who was playing Beer Bong.

Matt got a boner in a room full of men.

Matt said he'd "tap that", to a guy in his dorm.

Due to excessively high testosterone levels, a man with this syndrome will act in a gay manner when there are no females present. In other words, they are extremely horny... all the time. For example, suggestive comments or gestures, humping, wearing man thongs amongst men, winking at other men, caressing another man's body, and excessive physical contact are all symptoms of the "Man Thong Syndrome." These dudes ARE NOT GAY, they just require massive amounts of sex, ass, vagina, or anything else they can get.
