I'm going with the Anderson Drop. Hobbs is next up because you can tell Arn taught him the art.
You could argue that Booker's Scissor Kick is the blackest move. I can't even imagine a non-black person doing it. Even R-Truth makes is look cool cuz he like spins out of it. But yeah i don't think ive ever even seen a non-black person do a scissor kick.Ron Simmons' Spinebuster looked like he was trying to drive his opponent to the center of the earth so Imma go with that one.
Side note, is the Spinebuster the blackest move in wrasslin?
