A coworker or boss who chooses sides on any given issue based solely their desire to fit in.
Sanchez totally sided with the staff accountants in that meeting so they would give her a "you go girl!" in the company cafeteria. Last week she chose to hang with Legal so she could be invited to their Happy Hour. She's a total poser!
Someone that is not who they say/think they are.
The narcissistic girl saw a badass shark when she looked in the mirro and thought that everyone else could see in her what she saw in herself, but they were looking at her spirit and not her appearance, and all they saw was a plain and bossy poser that everyone had tried to keep from drowning her entire life.
Someone that thinks they are a lot spookier/scarier than they actually are.
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 thinks a beanie with a crocheted brim makes her look tougher.
The girl thought she was really a newsboy because she had a beanie with a crocheted visor that the salespeople called a newsboy hat. She thought if she was seen in a hat like that, people would walk on the other side of the street when they saw her, and she thought that way because she was a poser.
Someone that has to have a camera on them at all times to prove they are who they claim to be.
The poser couldn't go skydiving or do anything else without a camera, because having nothing to show for it wouldn't make her look tough or colorful anymore, she would be uninteresting, as everybody is throughout most of their lives. People are interesting for a little while after they are born, then they are interesting again late in their life, but most of their life there's nothing interesting about anyone in particular.
Someone that tries to make himself/herself look subserviant or put upon to a wide audience/crowd (for the image he/she wants to show publicly to gain an army that will combat an enemy), even though behind the scenes a lot of people in their life have done a lot of things for them without having gotten paid or credited for, and haven't asked to get paid or credited for.
He/she lived his/her life as a poser and a coward, and would even admit to being a coward when a large crowd wasn't around since it wasn't an incriminating thing to say about himself/herself, but when a crowd/group/party/gathering that he/she had a reputation with was around, he/she was all of a sudden tough as nails, a walking stick of dynamite, or anything he/she claimed to be.
Someone from a town outside of a city that claims the city as her own to gain support/benefit from doing so, and to be inflammatory towards any people originally from the city that oppose her instead of compromise with her.
The bubbly girl was a poser that lied about every aspect of who she was and her life to make herself (her image) look put upon, like an underdog instead of a bully (since some people might unwittingly support or defend her that way).
