Guy 2: "Have you ever seen her in person?"
Guy 1:"No, does that matter?"
Guy 2: "Better make sure she's not a catfish.."
Guy 1: "You think she's catfishing?!"

Coatfishing 

Like catfishing, but when a person only has photos of them in a coat on their dating profile, so you wrongfully assume that they are in good shape.

Guy 1: "Bro, I met up with my Tinder date last night and she was coatfishing!!!"
Guy 2: "Sorry to hear that man, you gotta be more careful next time"

Social Catfishing 

The process in which a social media manager creates multiple fake profiles only to engage with brands in order to boost the brands popularity. Also the practice of a social media manager liking and commenting every status that is written from every brand page he or she is in possession of. See catfishing

If I manage Facebook Pages for Clients A,B,C,D and E, I should have them all talk to each other all hours of the day on Facebook to portray the appearance that my clients have deep relationships with all these brands and endorse everything I say too. It would also be a good idea to have them sell anything I can profit from. It's like catfishing for social media, only it's Social Catfishing.
