A word gay/bi men use to describe themselves in a cool way that they are closet cases and have no intention of coming out soon. This allows them to maintain perceived heterosexual privilege while engaging in their true sexual desires.
"Are you out?"
"No, I'm totally discreet man. I got a girl...she can't know about this."
"Ah, ok I guess I'll keep looking."
"Not into flamers anyway."
"Who says I'm a flamer just because I'm out?"
"Stereotype. You should really come out man."
