What 뭬 means
It contracts the Korean question 무엇이: “what is it?”
뭬 is one Hangul syllable block, built from initial ㅁ and vowel ㅞ. Hangul is the alphabet created to write Korean; its development was completed in 1443, and the manuscript that introduced it appeared in 1446.
The form developed through 뭣이 → 뭐이 → 뭬, as final ㅅ was lost in the 19th century. A 1932 magazine dialogue already uses 뭬야 and 뭬냐; that dates those spellings, not the syllable's invention.
Why did someone send me 뭬야?!
They are acting shocked, usually with comic or theatrical force.
뭬야?! makes the question sound like disbelief, a challenge, or mock outrage; it is not a neutral way to ask “what is it?” The Korean historical drama 여인천하 aired in 2001–2002 and made the line a remembered catchphrase. A friend may be quoting that performance; otherwise, it still reads as an exaggerated “What?!”
As a contraction, 뭬 is grammatical; 뭬야?! sounds theatrical or deliberately overdone.
Avoid 뭬야?! as a plain question to a boss; its mock-anger tone can sound disrespectful.

2Is 뭬야?! rude?
It can be. The phrase may sound like mock anger or performative disbelief, so save it for a shared joke rather than a formal request.
Why does 뭬 appear as separated Hangul letters?
Usually, the text is not being shaped as a syllable block. Unicode can store Hangul as precomposed syllables or joining letters; a compatible font and text engine should combine ㅁ+ㅞ. Try a Korean-capable font or normalize to NFC, which joins canonically equivalent sequences.
