A brain poser highlights the act of "posing" as intelligent. It combines "brain" with "poser," immediately signaling someone who's faking intelligence.
"He spent twenty minutes using all sorts of fancy jargon, but it was clear he was just a brain poser trying to impress the boss."

This guy is a poser, the boy is quick to say he fought with people he never met, its a lot easier said than done.

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.

Guy that thinks he's Leonardo Di Caprio at the bar- TIA, right my brew.
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.

Someone who thinks that if you like yourself even a little bit, or you like where you're from, or you like your life, that you're prideful because you dont think the way they think, you dont think everything in life that doesnt have dollar signs to go with it sucks.
Nobody was going to miss the poser telling them about freedom and life while trying to gain more power.

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.
