Catfishing is creating a fake online persona to deceive someone — most often into a relationship, but also for money, harassment, or simple experiment. The person you're talking to doesn't exist as described, and the photographs usually belong to a real stranger who never consented.
The online-deception sense originates with the 2010 documentary Catfish. Contrary to a common claim, it does not predate the film — what predates it is an unrelated catfish-and-cod parable.
// Where it sits
Catfishing sits at the far end of online dishonesty — not exaggeration but invention.
What it really means
Almost every word in modern dating slang describes a way of behaving badly toward someone real. Catfishing is different in kind: the person on the other end of the conversation does not exist. The photos belong to somebody else, the job is invented, the voice on the phone — if there is ever a voice — belongs to a stranger with reasons of their own.
The word arrived fully formed from a 2010 documentary, and the story inside it is worth knowing because it's almost certainly false. In the film's closing minutes, someone explains that live cod shipped from Alaska to China arrive mushy unless you put a catfish in the tank to keep them darting about. It's a lovely image for a person who keeps everyone on their toes. It is also, marine specialists say, not a thing anyone does — the anecdote traces back to a 1913 essay used as a religious allegory, revived by preachers decades later, and eventually repeated into a documentary as though it were fact. The most famous word in online deception rests on a parable.
What separates catfishing from the softer fictions people tell on dating apps is that it isn't exaggeration, it's invention — and that difference has teeth. A kittenfisher uses a flattering old photo and turns up anyway. A catfisher constructs someone who can never turn up, which is why the tells cluster: video is impossible, meeting is always next month, and — where the motive is money rather than attention, revenge or experiment — sooner or later there is a crisis that money would fix.
If that pattern is unfolding for you right now, the practical steps are unglamorous and effective. Ask for a live video call. Reverse-image-search the photos. And treat any request for money — however sympathetic the story — as the point at which you stop and verify rather than help.
Where it comes from
The 2010 film retold the parable rather than inventing it: the cod-and-catfish story is in print by 1913, in Henry Nevinson's Essays in Rebellion and Charles Marriott's The Catfish. It is an urban legend about shipping, not a documented fishing practice, but it gave the word its logic.
How to recognise it
- They refuse video calls, or the camera always fails.
- Photos look professional, inconsistent, or reverse-search to someone else.
- The relationship escalates fast but meeting is always impossible.
- A crisis appears that money would solve.
- Details about their life shift quietly between conversations.
Myths & misconceptions
The term existed online before the 2010 documentary.
Investigations into the word's history found the opposite. Earlier uses are a religious parable about adversity keeping people alert — an entirely different meaning. The deception sense begins with the film.
The catfish-in-the-cod-tank story is real shipping practice.
It's very likely apocryphal. Marine specialists have found the scenario implausible, and its earliest known appearance is as allegory in a 1913 essay collection, not a fishing account.
Compare & contrast
Catfishing vs kittenfishing
A matter of degree with a real line between them. A kittenfisher is a genuine person using flattering, out-of-date photos — they'll show up. A catfisher has invented an identity, often with someone else's pictures, and typically avoids ever meeting. Impersonation on its own isn't a crime everywhere; what catfishing is usually used for — fraud, extortion — is.
| // | Catfishing | Kittenfishing |
|---|---|---|
| The person | Doesn't exist as shown | Real, just flattered |
| The photos | Often someone else's | Theirs, older |
| Will they meet? | Avoids it | Yes |
| Legally | Often fraud | Rarely criminal in itself |

Tell it apart
Questions people ask
- Where does the word catfishing come from?
- The 2010 documentary Catfish. Its closing scene contains an anecdote about shipping catfish alongside cod to keep the cod lively — offered as a metaphor for the person doing the deceiving. The story itself is probably not true, but it gave the word its shape.
- Is catfishing illegal?
- Impersonation on its own isn't universally criminalised, but the things catfishing is typically used for — fraud, extortion, offences involving minors — are crimes in most places. Laws vary by country and state. If money has been taken or you're being threatened, report it to your national fraud or cybercrime service; this page is educational and not legal advice.
- How do I check if someone is catfishing me?
- Ask for a live video call — an invented identity usually can't produce one. A reverse image search on their photos is quick and often decisive. And treat any request for money, however sympathetic the story, as the moment to stop and verify. If money has already changed hands, report it — in the US that is ReportFraud.ftc.gov, and elsewhere your national fraud reporting body.
- Is catfishing a mental-health condition?
- No. It describes a deceptive behaviour, not a diagnosis, and nothing here should be used to assess anyone. If being deceived has left you shaken — which is a common and reasonable reaction — talking to a counsellor or a mental-health professional is a fair step, and a fraud-support service can help with the practical side.
