MM meaning in text: MM is a short, informal response used in texting and online chats to show thinking, hesitation, mild agreement, or uncertainty. It often sounds like someone humming mm while deciding what to say next.
In simple terms, MM means “I’m thinking,” “maybe,” or “I’m listening”, depending on the context and tone.
You send a long message.
You wait.
Then you get one reply:
“mm”
No punctuation. No emoji. No explanation.
Is that a yes? A no? Are they bored? Thinking? Ignoring you politely?
If you’ve ever stared at your phone wondering what does mm mean in text, you’re not alone. This tiny two-letter reply carries a surprising amount of meaning, and it changes based on tone, relationship, and context.
This guide breaks it all down—clearly, casually, and completely—so you’ll never misread “mm” again.

Over time, mm became a universal low-effort reaction in texting culture.
