Indeed it does but Roger Mayweather was called that also. Pacman is more unique, it references his names but also the way he makes fighters look like ghosts of their former selves and munches them up in one fell blow! I AM NOT A NUTHUGGER. Just making a humerous observation of why that is an apt nickname.
Of course Pac has 'exceuted' the far superior Mexicans to Roger and could easily me the more prominent fighter with that nickname.
