What does FOMO mean?
FOMO means fear of missing out. It describes the uneasy feeling that other people are enjoying an experience or opportunity without you.
Also written: fear of missing out · fomo
The meaning
The focus is the possibility of being left out, not proof that you made a wrong decision. Seeing friends' photos or hearing about an event can make an ordinary evening feel inadequate by comparison. The word also applies to opportunities beyond parties, whenever someone worries they will miss something interesting or desirable.
What’s the tone?
Anxious, regretful, or lightly self-mocking.
When and how to use it
Use it to describe your own reaction to a missed invitation, an event, or other people's updates. A casual mention can be humorous or serious. Explaining what you feel excluded from makes the abbreviation easier to understand, especially for readers who have not encountered it.
In a conversation
Original examples to illustrate the expression.
Everyone's posting photos from the night market.
I'm getting FOMO, even though I wanted a quiet evening.
Let's plan a visit together next week.
Easy to misread
FOMO is not the same as knowing you were deliberately excluded. It describes a feeling or concern. It also differs from ordinary curiosity about what friends are doing.
A little context
Both dictionaries expand the abbreviation and describe missing an enjoyable activity or opportunity. The concept can occur offline as well as through social media, so this entry does not make it platform-specific.
