A truely superior being who lives, breathes, eats, pisses and shits wasabi. Their veins run with wasabi. They use wasabi as lubricant on their condoms. Wasabi Masters are able to do wasabi-type attacks, such as Wasabi Wind Attack, which blows wasabi, in the form of gas, into the faces of weaklings who cannot handle wasabi and it's incredible power.
Steve-O would've been on his way to achieving "Wasabi Master" status, if he didn't throw up after snorting some of that green shit.
