Someone who acts like they're from Baltimore even though they're from outside Harrisburg. Someone who has not only a thousand different screen names or online profiles, but also has fictional hometowns or current locations, fictional lives to go with them. A poser tries to outdo other people at silliness while trying to get taken more seriously than everyone else.
The poser was always this and that, always under somebody else's skin to make himself/herself look/feel more authentic. The poser wanted an authentic image.

A common misspelling of the word "Poseur", used to define someone who pretends to be something he/she is not. This type of person generally prescribes to a particular social group, in order to be trendy or popular; but does not really believe or practice anything that particular group does.
"Hey guys. I just wanted to let you know, I've become emo over the past couple of weeks."
"Really? What bands are you listening to nowadays?"
"Miley Cyrus and The Jonas Brothers."
"Screw you Poser."
"Screw you asshole. It's spelled Poseur."

This guy named ChEFF Tron. He's a huge fake ass poser. This guy thinks he's clever and smart but has no genuine characteristics of his own. He tries to act like a high and mighty holy roller but that's as phony as his personality. He won't shut up about how hot his 150 year old wrinkled ass mummy of a wife is either. This idiot thinks because everyone smiles to his face that they're not talkin shit about how stupid he is behind his back. He has no real friends just people that tolerate him.
Ah shit, here comes Poser ChEFF. Did he see me? Ah Fuck, he did! Just smile and laugh and try not to punch him in his phony ass face.

Someone who tries the rebellious teenager image even though they were always the goody two shoes who behaved exactly within the rules as expected by authority figures, and got other people in trouble or spied on them as a kid.
