The effect comes from Super Smash Bros Melee, released in 2001, where the Home-Run Bat item produces a loud, distinctive crack when it launches an opponent. That sound became widely reused outside the game in edits and fan animations, including Pretty Blood, a fan-made series built around cute Malino animals in violent situations where Rinny is a central character. Its instant recognition among Smash players and meme editors helped it spread as a shorthand for a devastating cartoon hit.
