Wario was introduced as Mario's greedy rival in Nintendo games and became a playable racer in Mario Kart 64 for the Nintendo 64 in the mid 1990s. His short voice lines from that era, recorded with exaggerated grunts and laughs, became memorable because races repeated them constantly during multiplayer matches. As retro game clips spread through YouTube, streams and soundboards, this Eh Eh Eh Eh taunt was isolated as a standalone reaction. It remains popular with creators who grew up with the Nintendo 64 and use retro voices to signal playful rivalry.
