One who enjoys going to extremes to enjoy and pleasure themselves, wether it be with men or a can of anal lubricant
He's M17 yo...
Are You M17
I want to be just like M17
A word used to describe a person with infinite sexyness. A person with M17 will go for hours - and won't care if it's with a boy or a girl
"That girl I was with last night sure had some M17"
