Anything that you've learnt from Bear Grylls (man vs wild)but you used it in a real urban environment (most likely whilst being drunk)
When you cant get in your mates house after a big night out so you make a nest out of branches on the driveway and make a fire from your mcdonalds bag.
THATS BEAR GRYLLIN-IT!
An adjective, referring to Bear Grylls, the British man who is a former member of SAS, the world record holder for being the youngest British person ever to climb Mount Everest and survive. Bear Grylls is also the host of the Discovery Channel program "Man Vs. Wild." On this program, Grylls constantly risks life and limb to demonstrate how to survive in different climates and situations. The term "Bear Grylls" is used to describe something incredibly daring, brave, manly, or just rediculously awesome.
The most badass motherfucker ever. Best known for his show, Man Vs Wild on the discovery channel. This guy will do anything possible to survive while trying to get out of a certain harsh environment. Such as, drinking your own piss or eating a sheeps eyeball. Although there are claims of his show being "fake", it's still very educational and helpful.
