Get the flatlinemug. A group of male beings that have a love for wanking and drinking till they are completely fucked out of their minds. They aren’t the smartest of all people, they are known to make out with lizzards on the wall and get drunk until they start beating up someone. They have a soft spot for a little thing called “cactus jack”.

Get the Flatlinersmug. 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.

Get the Flatlinermug. 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."
