Somebody that lies about every aspect of their life, what they believe in, what they feel, and who they are. Somebody that has an endless amount of false names, not false screen names or something mostly benign, something a bit more malicious, but has many false names in real life and claims each one of them is his/her real name.
The girl was the kind of poser that didn't want anyone to accurately identify her, so she had numerous false names and looked like a different person on the outside almost every time you saw her.

Someone who starts claiming to be an asshole to avoid being the same mollycoddle next door or down the street they were growing up, rather than because they really are an asshole.
The poser is imitating assholes now that he/she is no longer imitating kind hearted people.

Someone who is not who they say they are.
The girl with the can of spinach tattooed on her arm would act like she was from the South Side of Chicago even though she wasn't even from Illinois and didn't live a day on Central time as a kid. She wanted to show people how much tougher she was than them, that was why she did all this poser stuff.

The incorrect spelling for the word "Poseur". But if you must know, a poser is

pos·er pṓzər
(plural pos·ers)
(n) Someone who poses for a photograph or a work of art.

Look it up.

Although, a 'poseur', if that is what you meant, is

po·seur pō zúr
(plural po·seurs)

(n) A Pretentious Person: somebody who tries to impress others by behaving in an affected way

I'm unsure why people changed the spelling of it, but it is frowned apon. You have just made an ass out of you and me.
1) someone who poses (aka poser)

2) same as poseur (informal)
