The phrase works online because it turns a simple question into a meme reaction, and short clips of it circulate widely in reaction videos, TikTok edits and gaming highlights where creators want to flag something absurd without explaining it.

Because it is brief and instantly recognisable, it remains a handy shorthand for disbelief in fast-paced social video.
