FOMO means fear of missing out. Dictionary.com defines it as anxiety or insecurity about missing an event or opportunity, and says it was first recorded in the early 2000s. People use it in messages and posts, and marketers use it in campaigns. Used honestly, with real deadlines, it can help people decide.
FOMO is one of those words that jumped from slang into everyday English so quickly that people now use it in boardrooms and bakeries alike. Your customers use it, your teenagers use it and marketers use it as a tactic, sometimes well and sometimes badly. I'll explain what it means, where it came from, how people use it in messages, and how a business can bring FOMO into its marketing without misleading anyone.
The meaning of FOMO
It's short for "fear of missing out". Dictionary.com defines it as a feeling of anxiety or insecurity over the possibility of missing out on something, such as an event or an opportunity. It describes the uneasy feeling you get when you think other people might be having a good time, or getting something good, without you. Dictionary.com also notes that in the digital age it often leads to constant checking of social media to see what friends are doing.
It's a word for a feeling, not a diagnosis, and I'm not going to offer wellbeing advice here. If it's causing someone real distress, a doctor or a qualified professional is the right person to talk to.
Where the word FOMO came from
Dictionary.com says FOMO was first recorded in the early 2000s, formed from the first letters of fear of missing out. Wikipedia credits Patrick J. McGinnis with coining the term and popularising it in a 2004 op-ed in The Harbus, the magazine of Harvard Business School, where he was then a student. The same article mentioned a related idea, fear of a better option, known as FOBO.
Wikipedia also notes that the phrase "fear of missing out" itself is older than the acronym. It says marketing strategist Dan Herman used the phrase in presentations in the late 1990s and in a 2000 paper about short-term brands. Wikipedia adds that the term has been used as a hashtag on social media and mentioned in hundreds of news articles.
How people use FOMO in messages and posts
People use FOMO as a noun, as a joke and as a reason for doing things. Here are the usual patterns, followed by invented examples (none are real messages):
- Admitting a feeling: "Seeing everyone at the festival, I've got serious FOMO."
- Explaining a decision: "I only bought a ticket because of FOMO."
- Teasing a friend: "Don't leave me out, I get FOMO."
- Describing an offer or event: "Limited places left, don't get FOMO."
- As a hashtag: #fomo, often on photos of parties, trips or launches.
Example: "Skipped the gig tonight and now my feed is full of it. FOMO is real." Example: "Not going to lie, FOMO is the only reason I signed up for the webinar." Example (from a shop owner): "We only have a few spaces left on Saturday's workshop."
Words that sit close to FOMO
Several terms describe nearby feelings. Here's how they compare:
| Term | Meaning | Where you'll see it |
|---|---|---|
| FOMO | Fear of missing out | Social media, marketing, everyday chat |
| FOBO | Fear of a better option | Decisions, dating, shopping, events |
| Bandwagon effect | Doing something because others are | Trends and group behaviour |
| Keeping up with the Joneses | Matching what neighbours or peers have | An older phrase for a similar feeling |
Wikipedia mentions all of these in its FOMO article, including the older phrase about keeping up with the Joneses, which it describes as a related phenomenon before the Internet. It also notes that FOMO shows up in social media, video games, investing and marketing.
FOMO in marketing and how to use it ethically
Wikipedia says advertising and marketing campaigns may seek to intensify FOMO, and it gives examples from well-known brands that suggested people would be left behind or miss updates without the product. It also notes that other brands deliberately counter FOMO. That tells you something useful: the tactic is common, and so is pushback against it.
Used honestly, FOMO is simply a way of saying that something is limited or time-bound, which is often true. Used dishonestly, it's manipulation, and customers spot it fast. Here's how I'd keep it ethical:
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
- Only mention a deadline if it's real. If registration closes on Friday, say so, and close it on Friday.
- Only say places are limited if they are. Give the actual number you have.
- Never invent a countdown timer, fake 'other people are looking at this' notices or made-up demand.
- Describe what people will gain by joining, not just what they'll lose by waiting.
- Make it easy to decline without feeling bad. Trust matters more than one rushed decision.
- Give people the information they need to decide. Pressure without facts is the opposite of helpful.
For a practical example, the digital marketing events roundup I wrote used the word as a playful hook for a real list. That's the sort of FOMO that works, because the readers really wanted to know what was on.
Should a brand say FOMO in a post?
As a word, FOMO is widely understood, so it suits most casual audiences. It's less suited to formal or very senior audiences, who might find it a touch glib. It works best when the thing you're promoting is real, such as an event, a limited run or a time-bound opening. Be careful about using it to describe your own followers' feelings, such as "Don't miss out on what everyone's talking about". That reads as pushy.
If you promote events or launches on social platforms, hashtags that work on TikTok and Instagram and trending hashtags on Facebook Reels can help real news reach people, and a good link in bio tool keeps sign-ups in one place. For the slang around it, see how Stan Twitter talks.
Replying when someone mentions FOMO
If a friend says they've got FOMO, a kind reply goes a long way: "Next one, I'll make sure you're there." If a customer mentions it in a comment, treat it as interest. Answer their question, share the details and let them choose. They've told you they care, so you don't need to add pressure.
