Fec

Someone that's putting on an act in a place they normally wouldn't belong with good intentions

The goal of a Fec is to be able to slide into a character they play to fit in with a culture and slide out without being noticed
Only people with high confidence, social skills and street knowledge can pull off being a Fec without being exposed as a Fec (requires what some call aura, realted to rizz)
Calling someone a Fec can be an insult when the person is posing and not admitting
Calling yourself a Fec or someone using Fec in a postitive way can be compliments

Positive:
"That guy is def a Fec, he's a cop but he's off duty so he's prob not a rat"
"I'm a Fec, I've got so much aura that people don't even know who I really am"
"I saw Brenden hanging out with Daquavion and Jamal, but he's a Fec not a poser"
Negative:
"Bro's switched up to get attention from the girls, he's a Fec no cap"
"Nah he's not really about the streets, he's just a Fec"
