Waluigi is Nintendo's mischievous Mario-series rival, first appearing in Mario Tennis in 2000 and becoming a fan favourite despite rarely starring in mainline games. His exaggerated confidence and underdog status have made him a natural subject for fan edits, remixes and meme audio, where his boastful persona is pushed to comic extremes. Short clips like this one circulate on soundboards and in gaming videos because they capture that persona in a single memorable line, letting creators borrow his swagger without needing a longer scene.
