Extreme catfishing; The act of not only catfishing, but doing so on a level so intense or with so many fake profiles that Nev Schulman would be shocked.
Jessica: I was totally catfished by a girl in my English class! I thought my boyfriend Chris and a few of his friends on IG were music producers but they were all fake profiles by this chick so she could get with me!
Margret: OMG, she wasn't just catfishing you- she was tigersharking you!
In online dating, the opposite of a catfish. It is when the person you meet from an online source actually turns out better looking in person. Sometimes so much that their pictures don't look like them but instead of leaving, you stay.
Girl: Hey how was your date with that guy from tinder?
Other girl: It was actuallypretty good. I was worried because his pictures were kind of meh. But he was a total tigershark in person. I'm seeing him again tonight.
