Aerial Knee Smash comes from Street Fighter 6, Capcom's fighting game released in 2023. The clip bundles the move's impact sound effect with the fighter's spoken voice line, the same way the game presents special moves in a match. Fighting game channels and short-form editors picked it up for combo videos and versus memes, where a recognizable game voice line sells the hit harder than a generic punch. It stays in rotation because Street Fighter 6 remains a staple of tournaments and online play.
