Meh?

Tree got me alarmed when the word "meh" is finally accepted as an English word.

I firstly thought that it was referring to the Cantonese exclamation of "Meh":

Meh (/mɛ́/), from Cantonese, is used to form questions expressing surprise or scepticism:

• They never study meh? – Didn't they study? (I thought they did.)
• You don't like that one meh? – You don't like that? (I thought you did.)
• Really meh? – Is that really so? (I honestly thought otherwise.)

which is also widely used in the Singlish dialect. But nah, it wasn't... For you Singapore folks, feel free to check out the articles on what the word "Meh" means to the Americans.
