Meh

Meh is an interjection used as an expression of indifference or boredom. It may also mean "be it as it may". It is often regarded as a verbal shrug of the shoulders. The use of the term "meh" shows that the speaker is apathetic, uninterested, or indifferent to the question or subject at hand. It is occasionally used as an adjective, meaning something is mediocre or unremarkable.

Other uses

Meh is popularly used as a catchall answer to any question. It is acceptably interchangeable with most responses.

Also considered a non-committal response, “meh” can be used when disregarding a question or to refer to something they have no opinion or emotions about. In expressing an opinion, it means the speaker's opinion is that of apathy. However, some may respond with “meh” simply to avoid creating an opinion on the matter at all.

Origin

The origin is unknown. Some have speculated that the term's origin is Yiddish because of its similarity to the interjection "feh", which appears in the 1936 Yiddish song Yidl Mitn Fidl. The rhyming of the two words is only one such link to the language. In Alexander Harkavy's “Yiddish-English-Hebrew Dictionary” the word is treated as a bleating or baa sound. Hooray for Yiddish, by Leo Rosten uses the word “mnyeh,” which is speculated to be an early variant of “meh.”
