The sound comes from Resident Evil 4, the survival horror game first released by Capcom in 2005, where the mysterious Merchant runs a travelling shop and greets Leon Kennedy whenever the player approaches to buy or upgrade weapons. His warm, slightly unsettling welcome became one of the game's most quoted lines, and clips of it spread through gaming videos, streams and meme edits as shorthand for a shopkeeper, a deal or an unexpected arrival. It remains popular because it is instantly recognisable, even to players who have not finished the game.
