Waluigi debuted as Wario's doubles partner and Luigi's rival in Mario Tennis in 2000 for the Nintendo 64, and his exaggerated wah became one of his signature vocalisations across Mario Kart, Mario Party and sports spin-offs. The clip spread through gaming videos, remixes and soundboards because it condenses his whole sore-loser personality into under a second. Unlike a generic cartoon cry, fans hear it as specifically Waluigi complaining about being overlooked, which keeps it in use for gaming fails and reaction edits.
