The phrase comes from The SpongeBob SquarePants Movie, released in 2004, where SpongeBob embraces being a “Goofy Goober” during the film's musical climax. The Goofy Goober concept also appears earlier as an ice cream shop and mascot within the story. Short extracts of the line later circulated through meme edits, reaction videos, and soundboards because the wording is easy to recognize and fits absurd visual punchlines. It remains popular as a compact expression of cheerful immaturity, nostalgia, and wholehearted silliness.
