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."

My hobby is flatlining.
