Someone who starts claiming to be tough around the edges at some point as an adult, though it's not who he/she is or was as a kid.
The poser kept posing as somebody with a rough edge, even though giving intel (or counter intel) to teacher's and authority figures, and other shit that he/she did as a spy kid was closer to his/her own definition of smooth, always evading trouble for himself/herself while getting everyone else in trouble. Really, the poser's rough edge image was created as a defense to keep people from messing with him/her like they did when he/she was a kid.

Get the Posermug. You can tell a poser imitating a kind hearted person from a kind hearted person, since a poser wont pose as kindhearted without also adding something about themselves being badass to their claim of being kindhearted.
The poser would pose as kindhearted when he/she wanted acceptance from the kindhearted folks, and as an asshole when he/she wanted acceptance from assholes.

Bartender- No, not TIA, TIO. This is Omaha, I know because I am one of two black guys here. This is not Africa my man. I will not be a poser with you.
