The 'FBI open up' phrase grew into a popular internet meme used in short videos and edits where a scene is interrupted by a mock raid. Creators pair the shout with an explosion to exaggerate the entrance, turning jokes about forbidden content, secret tabs, or suspicious behaviour into a sudden police bust. Its spread was driven by TikTok, YouTube Shorts, and meme soundboards, where the short, recognisable setup works even out of context. Because the joke is instantly understood, it remains a go-to punchline for surprise reveals.
