A poser is someone who tries to fit into a profile they aren't. People who try to give off the impression that they are one thing when they are really another.
Also, a poser can be one who says they can do something that they can't.
Or more commonly, a poser is someone who, when doing something successfully, takes more than enough credit for it.
Lots of types of Posers, for example The guys who hang out with skateboarders but can't actually skate, even though they have a board.
