A maneuver in football or any contact sport where one player (normally defensive) holds another player from the opposing team up, while the another defensive player hits him while his feet are off the ground. The breakdown of the word would translate the "Wha" as being the part where the player is held up and the "Wham" as being the part where he is hit by another player.
The Wildcats defense held up Louisville's running back then all of the sudden..."WHA WHAM", another Wildcat player leveled him
