The phrase ne diyo is colloquial Turkish for what is he saying, and the extra vowel in diyoo reflects how the word is stretched in the clip. The sound circulated as a short reaction audio on soundboards and in meme edits, especially among Turkish speaking users, before spreading to wider short video platforms. It is now used less as a literal question and more as a shorthand reaction, similar in spirit to a confused huh moment, whenever a statement needs no real answer, only disbelief and comic timing to underline the confusion.
