Meaning of Idiom 'Big Deal'

A big deal is something that is very important, special, or a matter of great interest. 1, 2,3

This idiom can also be used to mean "who cares?" or to express, ironically, that one does not consider a matter important or notable.


This idiom is most often used in the negative, in the form of "it's no big deal" or simply "no big deal." In fact, it is used in this way so often that it may be appropriate to consider the negative version the primary idiom and big deal itself, a variation. Also, when "big deal" is used as a standalone utterance, it is often ironic or facetious and it meant to convey the opposite of the first meaning given above, that something that has been represented as important is not important (or impressive) at all.

Similar is the phrase "to make a big deal (out of something)." This is usually meant to convey that something unimportant or trivial has been represented or reacted to as if it was of great importance or very impressive or notable.
