Someone who's not really a troublemaker, but wants more than anything in the world to be accepted by the world, so does everything a troublemaker would do, thinking that being one is the answer to the question of what's wrong. A mama's boy or mama's girl posing as a rebellious teenager their entire life, well after their eighteenth birthday.

Get the Posermug. 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.

Get the Posermug. If a guy has convinced people he's Italian (such as an actor in a movie), but he's not really Italian, no matter how believable the guy is, he's not authentic, so he's a poser.
The poser had convinced people that he/she was from hell and that he/she was hell, but since there was no hell, he/she was just another otherwise obscure poser.

Get the Posermug. A dedicated fan of Lego, retro video games, and vinyl during lockdown but has since went back to his craft beer flights, indoor axe throwing, and pickleball.
"Dakota is such a COVID poser. As soon as lockdown lifted, he went right back to being a gentrified sheep"

Get the COVID posermug. 
You hear all the time about white guys who wear Fubu and act like they are from Compton. You never hear a song about a white guy who dresses like one of the tribe in Sierra Leobe and talks the way Leo DiCaprio talks at times in Blood Diamond.
Poser- What's up my brew? Let me get a cigarette about of dem pack in your pocket mon.
Other white guy- What the fuck is wrong with this poser?
Third white guy- I don't...
Poser- My name is dead body mon, don't call me poser mon.
Third white guy- At least he has more imagination than most posers, he's trying even harder than the guys that act like they're from Compton.

Get the Posermug. Dave: "Steve is such a poser."
Mark: "You mean he poses for pictures like a model?"
Dave: "No, he tries to be something he isn't."
Mark: "You mean a poseur? You're an idiot, dude! You told me you're smart. I guess that makes you a poseur."
