The narcissistic girl saw a badass shark when she looked in the mirror, and thought that everyone else could see in her what she saw in herself when they looked at her, but they weren't looking at her appearance, they were looking at her spirit, and all they saw was a plain poser that everyone had always been trying to keep from drowning.

Someone that is not who they say they are. Someone that tries to discredit a company (UPS, a retailer for examle) because they didn't get as much money as they wanted for something.
The girl was trying to discredit the company to defend her feisty (and false) image. Someone that really is feisty doesn't have to tell people around them often about how feisty they are to get attention or attempt to scare the shit out of people, and anybody that does that, big or small, is a poser.

An infamous hacker from the 2013 tumblr days of instagram/tumblr who nicknamed herself "the poser queen" and posted pictures of herself. Nobody really knows if the girl in those pictures were actually her or she was just catfishing someone random.
Donny: hey, you heard about the poser queen yet?
Sid: no, who’s that?
Donny: she hacked my tumblr account in 2013, man! It was crazy! I found her Kik too, bro!"
Sid: no, who’s that?

Someone who always tries to kick somebody out of somewhere or something (or get them kicked out) and look badass while doing it.
The mall cop rolled up his/her sleeves so that he/she could show off his her tattoos (and power) to everybody in the group, and told them they must have a death wish by being there at the mall, since nobody was allowed in his/her mall after 5 PM. The extreme poser got off on kicking people out of public places.

Someone who thinks they're making a major statement or changing the world every time they do something an asshole would do, like it's their first time being that way and they have to do/outdo more to prove they are an asshole to other assholes than everybody else.
The poser thought everything he/she said that an asshole would say needed to end up as a quote online somewhere, otherwise people would remember what he/she was like growing up.

Even if he/she filed his/her teeth down into serrated edges and wore black contacts, he/she still wouldn't have anybody convinced that he/she was really a shark. He/she was a poser, posing as a man eating denizen of the seas.
