Purporting to be someone or something you are not on the
Internet in order to gain
friends, attention, partners, pity, sympathy or
money. Named after the faux-documentary "Catfish", Catfishers have been known to post fake pictures of themselves (including but not limited to catalog images), claim to have a dying fiance or mother, or create an entirely fictional version of themselves.
Uh oh, did you see that perfectly posed photo of
Donna she posted?
That girl is so catfishin'.
Oh man, I heard Northlad's girlfriend is really sick. I
sure hope he isn't catfishin' us.
