PSI Rockin originates in EarthBound, released as Mother 2 in Japan in 1994 and in North America in 1995 for the Super Nintendo. It is the signature offensive PSI move of the hero Ness, named after the player's favorite thing with Rockin as the default. As EarthBound built a lasting cult following and Ness stayed visible through the Super Smash Bros. series, its battle effects were ripped and shared on soundboards. Fans still use this short zap to reference the game instantly without needing music or dialogue.
