The spike move (down-a in the air) for Captain Falcon in Super Smash Bros. 64. When an opponent is off the stage in mid-air, jump up and press down-a upon contact and the opponent will rocket downward for an INSTANT KILL!
It's called a clown stomp because cap'n falcon looks like a crazy clown with all his different colored suits.
you want a... CLOWN STOMP??!!!
