The line comes from the SMG4 video in which Mario reacts to Nintendo memes alongside Meggy, a format that mixes game parodies with fast, self-aware humour. Lifted from that reaction, the short phrase travelled as a standalone soundboard clip, shared by fans who wanted a quick way to signal nostalgia without a long setup. It has stayed popular because it is instantly recognisable to Mario and SMG4 fans, yet simple enough for anyone to use over old footage, returning characters or a callback to an earlier joke.
