Flatliner

When you’re fucking a diabetic so hard her insulin pump fails sending her into insulin shock only to be revived by cumming in her mouth.

Hey Tina. I hope your glucose levels are in check or else we might have a flatliner.

Emotional Flatliner

Someone who shows no emotional response to anything, no matter how poignant or stirring. They’re either so repressed that nothing gets through their emotional firewall, or so disconnected from their feelings that even a child’s laugh, a heartfelt poem, a soulful song, or a breathtaking view leaves them completely unmoved. Picture a human equivalent of a flatline on an emotional EKG—zero reaction, just a blank stare.

"I played her my favorite song, the one that makes everyone cry, and she just shrugged—total Emotional Flatliner."

A "nation". I mean, who the fuck made this, Jacopo Castelletti? This whole micronation thing is just fucked up all together.

Get out, what are you? A Flatlandian?

Flatlanders

A term from people of higher elevations used against people if lower elevations such as cities. Most Flatlanders travel to the higher country for sometimes a week at a time to shoot deer with their "Flatlanders Special" (30-06). Flatlanders often get angry for no reason and miss deer.

"Hey Bren look, the Flatlanders followed us home because we were going 45 in a 35! Must have missed some deer this morning..."
