Whitest boy alive
Kind of like the noble savage, there is whitest boy alive, he doesn't exist. There is nobody as shy and naive as the description. People are just people, and the weak one is the one always looking for the weak one to try and walk all over or take advantage of, no matter what they look like.
There is no whitest boy alive any more than there is a blackest boy alive, though you don't hear many black guys arrogant enough to call some guy the blackest boy alive.
