Mooyaho (무야허)
Mooyaho is a recent reaction meme that’s blown up in Korea, used as a joyful exclamation of sorts. It comes from the show Infinite Challenge, where an old man was asked what the show’s tagline was; the tag is one person shouting ‘Muhan’ and the reply being ‘Dojon’, which corresponds to the show’s name in Korean. In the episode where the meme originated, the elderly man shouts ‘Mooyaho’ instead. It’s become a popular caption/meme recently on the internet.

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
