Waluigi has been a fixture of Nintendo's Mario games since his debut as Wario's lanky partner, and his exaggerated expressions have made him a favourite for memes and reaction edits. Short clips built around a single look or gesture travel easily between gaming streams, TikTok edits, and soundboards, where creators reuse them to signal mischief or suspicion without needing a line of dialogue. Because the character is instantly recognisable even to casual players, the gag still lands years after his first appearances, especially in Mario Party and sports spin-off edits.
