SNK is the Japanese game company behind the Neo Geo arcade system and series like The King of Fighters and Metal Slug, and its coin sounds became part of the shared language of arcades. As emulators, retro compilations and gameplay clips moved online, short insert coin effects were ripped and reused as standalone reactions. This one survives because it is instantly recognisable to arcade players yet simple enough for anyone to understand as money in, credit added, game on, even without seeing the original cabinet or game at all today.
