The line comes from the Spanish-language version of SpongeBob SquarePants, where Bob Esponja is the Spanish name for the title character. Short dubbed lines like this travel well on soundboards and social video because they are instantly recognisable even to viewers who do not know the original episode. Spanish-speaking creators have reused the triumphant catch as a shorthand for finally cornering someone, and its brevity makes it easy to drop into memes, edits and reaction clips without needing subtitles or extra context.
