This alternate version exists because short reaction phrases like this one are constantly re-recorded, remixed and re-uploaded by online creators, so several takes of the same line circulate side by side. The wording works as a universal shorthand for not knowing something, which makes it easy to drop into memes, commentaries and short videos without needing any context. Its appeal has lasted because confusion is a common, low-stakes joke, and a simple spoken line can sell that moment faster than a longer explanation.
