A guy who is in love with the japanese anime " death note ", his hand is his only lover, he does kali... Whatever that is. He lives in a cardboard box and uses dead cats as deodorant...jean-marc can be a synonym of the word "hobo" and also the word "assjuice"... Jean-marcs can be found in many places like under rocks, behind trees, in card board boxes, and also in caves.
When you see a man on the street with an underwear over his head and he is begging you to give him a cookie... That would be a jean-marc.
