This phrase is best known from SpongeBob SquarePants, where it appears as one of the show's time card transitions narrated in a distinctive voice. The series began in 1999, and these short transition cards became a recognizable part of its comedic pacing. Online, the sound spread through reaction videos, remixes, and short-form edits as a simple way to signal that time has passed. It remains popular because viewers immediately understand the joke structure: setup, pause, then a delayed or exaggerated payoff.
