Waluigi is Nintendo's lanky troublemaker, introduced in Mario Tennis in 2000 as Wario's doubles partner and a rival to Luigi. His exaggerated laugh, whiny voice, and self-pitying loser persona made him a favourite for memes even outside main Mario platform games. Short clips of his cackles circulate on soundboards and in gaming edits because the delivery is instantly recognisable without any context. The ha ha ha version is used less as a quote and more as a taunting reaction, especially for cheating, gloating, and petty victories.
