The line comes from Beesmas Cheers, a short animated movie by the YouTube creator YannisTH, where it appears as a comic voiceline between the bee and bear characters. Clipped by fans, the 1.4 second reaction found a second life on soundboards and in meme edits, where its blunt disbelief fits roasts, plot twists and out of pocket statements. Because it is so short and readable, editors use it as a verbal punch that needs no setup, which keeps it circulating in Christmas themed compilations and everyday reaction memes.
