A catfish is “any of an order (Siluriformes) of chiefly freshwater stout-bodied scaleless bony fishes having long tactile barbels” or “a person who sets up a false personal profile on a social networking site for fraudulent or deceptive purposes” [source].

According to Wikipedia, a catfish is “someone pretending to be someone they are not on the internet”. The term apparently became popular after the 2010 film Catfish, the story of a man who falls in love with a girl online who is using a false identity. However it was used for decades before then.

I only discovered the second meaning today when reading something a friend posted online. He talked about being catfished on a date, and I had to look up the term.

A few years ago I was catfished myself by someone on a dating website who claimed to be a Russian girl living in France, but turned out to be an online scammer looking for money. I didn’t send them any money, and got to practise my French for a few months, so it wasn’t an entirely negative experience.

A similar term is sockpuppet, which is “an online identity used for purposes of deception”, and was originally “a false identity assumed by a member of an Internet community who spoke to, or about, themselves while pretending to be another person”. It was first used in 1993, and can now refer to someone who praises, defends or supports a person or organization, manipulates public opinion, or circumvents a suspension or ban from a website [source].
