MMA pretender litmus test - how to spot a poser without sparring him?
A few days ago, I had the misfortune of running into a gentleman claiming to have trained BJJ for 20 years despite being British and in his mid- to late twenties himself. Over the next half hour, it became increasingly obvious that the young sir would not know a kimura from a coconut and was bragging of his MMA prowess while dissing it as not being street enough, yo, and talking up whatever RBSD/ninjer fads are hep with the kids these days.
This pissed me the **** off, mainly because it took me nearly 15 minutes to casually ask him about the specifics of his BJJ and MMA training, 15 minutes of me giving him the benefit of the doubt that I will never get back!
So the question I'd like to ask is: How would you determine beyond all reasonable doubt whether somebody is full of crap about their MMA/BJJ background in 3 minutes or less without calling them out? What single question would out them as being poser trash?
