The line comes from Waluigi in Mario Golf: Toadstool Tour, the GameCube golf game where Nintendo's lanky purple rival appears as a playable golfer who taunts opponents after their shots. His exaggerated voice and villainous grin made him a favourite for short reaction clips, and the Don't Whiff line was later lifted onto soundboards and meme edits where it could be dropped over any missed attempt. It endures because the joke is instantly clear even without the game context: a smug rival celebrating a failure.
