I just noticed in the taunt update one of the available lines is SNAAAAAAAAAAAAAAAAAAAKE!
You make your own, buddy. You type 'em in for your set control scheme, along with your name and preferred controller, and they go with the taunts you selected them to go with.
I never ever used handicaps in any of the other games, so this is just meh for me, but I guess it could make for some interesting matches.
