LittleBigPlanet is a 2008 PlayStation 3 platform game from Media Molecule and Sony, built around Sackboy, a small knitted character who can slap other players in its playful multiplayer levels. That slap became a recognisable in-game sound effect, closer to a cartoon punch than a realistic hit, and players later shared short clips of it on soundboards for use in edits. It remains popular because the effect is instantly readable, family-friendly, and short enough to drop into gaming videos, reaction clips, and meme edits without needing any context from the original game.
