What Does MHMM Mean in a Text?

MHMM means "Yes," but can also mean "Really?"

MHMM (pronounced as "Um-hermm" or "Um-humm") is an interjection commonly used in English to express agreement (i.e., to say "Yes"). However, depending on the emphasis placed on the syllables, it may also be used to question something that has just been said (as in "Really?"). Context is crucial to understanding the intended meaning.

When used to mean "Yes," MHMM can express emphatic agreement, but it can also indicate a lack of interest or enthusiasm. (See examples below.) In this context, MHMM is also often typed as MHM.
