The line comes from Star Fox 64, released for the Nintendo 64 in 1997, spoken by Falco Lombardi, the team's hotshot Arwing pilot. In the game he shouts it during dogfights when he is chasing the same enemy as Fox McCloud, cementing his competitive personality. Clips of Star Fox voice lines became a staple of early YouTube poops, memes and soundboards in the 2000s, and Falco's taunts carried over into Super Smash Bros. culture. Creators still use it today because it instantly signals playful rivalry in just over a second.
