A catfish is a person who sets up a false personal profile on a social networking site for deceptive or fraudulent purposes. The modern term originated from the 2010 American documentary "Catfish." According to Vince Pierce, the husband of Angela Pierce who deceptively creates an online profile in the documentary film, the term catfish comes from fisherman "putting catfish in with the cod to nip at their tails and keep them active" during overseas transport in order to produce more lively and fresh meat.
