A: How was the date with the gal you met online?

B: I was really falling for her on WeChat, but she turned out to be a catfish.

Note: Literally a “catfish” is a type of fish that has a large head and long thin parts that look like a cat’s whiskers around its mouth, but it also refers to someone who pretends to be someone they’re not, using social media to create false identities, particularly to pursue deceptive online romances. It has also become a verb to refer to the act of doing so. The term came from a 2010 U.S. documentary film “Catfish.” Towards the end of the film, Nev Schulman finally meets the woman with whom he’s carried on a long-term online relationship. She is, he discovers, not young and single, but in her 40s and married. By way of metaphorical explanation, the woman’s husband, Vince Pierce, says: “There are those people who are catfish in life. And they keep you on your toes. They keep you guessing, they keep you thinking, they keep you fresh. And I thank god for the catfish because we would be droll, boring and dull if we didn’t have somebody nipping at our fin.”
