This is the first I've heard the term catfishing. Can someone provide a more concrete definition? Is it simply pretending to be someone else online?

It originates from a movie, and is also now a TV show.

A catfish is someone who pretends to be someone they're not using Facebook or other social media to create false identities, particularly to pursue deceptive online romances.
