The line comes from the Shoop da Whoop internet meme, a cartoon face that opens its mouth wide and fires a huge laser, and the phrase became a shorthand for unleashing absurd power in videos, edits and soundboards. As the meme spread through forums, online compilations and reaction clips, creators kept reusing the voice line as a setup for a pew pew laser payoff, even when the original image was not shown. It survives because the joke is instantly clear: a silly warning followed by total overkill.
