Billy Mays was an American television pitchman famous in the 2000s for infomercials selling products like OxiClean and Mighty Putty. His shows almost always began with the greeting Hi Billy Mays here, delivered in his loud, upbeat style. After clips circulated online, that intro became shorthand for any exaggerated sales pitch and was widely remixed in parody videos and meme edits. It remains popular because the line needs no context, one hearing instantly evokes late night TV advertising and overenthusiastic selling.
