The ultimate in extreme sports, it requires you to wake up at 4 AM every single day and engage in grueling tactics and combatives training, and run a solid 5 to 10 miles a day while carrying about 80 pounds of gear on your person. Far manlier and more exhausting than any other "extreme sport" (i.e., a bunch of douche bags chasing after a ball all afternoon and feeling hardcore afterwards).
Bill: Yo, why are you so tired?
Ryan: Aw man, I've been training with the Ranger Challenge team. Working out like nobody's business and running on no sleep at all.
Bill: Yeah man, I was playing soccer for like ten whole minutes yesterday. I'm tired too, so I totally know how you feel.
Ryan: No you don't.

A YouTube stunt usually pulled off by urban African American youth, in which the person doing the challenge lights up weed (usually a blunt) in a public place i.e Walmart, subway, McDonalds etc. This is a risky challenge as to the obvious problem of possibly being caught or even arrested.

Even though I spent 5 minutes in the bathroom preparing myself for the Nibblers Challenge, I still laughed when I said "Nibblers".
