Wario is Nintendo's greedy, mischievous rival to Mario, first appearing in Super Mario Land 2: Six Golden Coins in 1992 and later starring in his own WarioWare and Wario Land games. His exaggerated voice and confident attitude made him a favourite for short reaction clips, and this good-luck line fits that persona perfectly. As soundboards and short-form video grew, brief character greetings like this one spread as quick inserts for streams and edits, where a familiar voice can set the tone in under three seconds.
