The 'Jellyfish Jam' meme originates from the 1999 SpongeBob SquarePants episode titled 'Jellyfish Jam,' where SpongeBob adopts a jellyfish that leads to an all-night techno rave in his pineapple home. The scene's infectious electronic track, 'Stadium Rave,' became an instant cultural touchstone for internet users. In meme culture, the template is used to represent overwhelming excitement, late-night energy, or situations where someone is vibing to music despite their surroundings. It often features SpongeBob throwing his hands up or dancing frantically, making it the go-to visual for anything high-tempo or celebratory.
