The sound comes from Resident Evil, where players regularly meet a mysterious travelling merchant who sells weapons, upgrades, and supplies between dangerous encounters. Fans nicknamed him the Buhonero, the Spanish word for a peddler, and his grateful, slightly unsettling thank you became one of his most quoted reactions. Clipped from gameplay and shared across meme pages and editing apps, it spread as a shorthand for a deal done or a favour accepted with a grin. It survives because players instantly recognise both the voice and the bargain behind it.
