The nickname/moniker of professional wrestler Ric Flair, who currently performs on Raw for the WWE. Often shortened to "Naitch" (pronounced Nay-ch) by ring-announcer Jerry "the King" Lawler.
"Oh my god, it's the Nature Boy Ric Flair, the dirtiest player in the game! What's Naitch doin' out here at ringside, JR?" (obviously up to no good)
Someone who pisses nature. A nature boy can often be found riding his bike to wildlife ecology classes on any nature loving campus such as University of Maine or Unity College. This breed of boy lives in flannel and smokes enough pot to make a columbian drug lord proud and due to excessive time spent hiking through the woods these boys have hot bodies. If you fit the above criteria and have dreadlocks you are the king of the nature boys.
Girl 1: Did you see Joe is slacklining out on the mall?
Girl 2: Oh yeah he is officially a nature boy!
when you are a guy that humps in nature-ish areas, such as trails, yards, and on fences.
when having sex with a natureboy, you end up screwing with dirt and sticks up your asshole.
