Flatline flip

The mother of all drug combinations. This is when a person takes LSD, MDMA, alcohol, caffeine, nicotine, prescription opioids, prescription amphetamines (substitute for meth if you’re bummy) (or cocaine if you’re rich which you aren’t) as well as some Benadryl to kill nausea.

This combo is not meant to be attempted by anyone who isn’t a professional drug addict.

If done right the stimulating effects of the Molly, Acid and rX stimulants should completely override the sedation caused by the alcohol, Benadryl and Opioids making you feel completely sober.

Honestly you will probably overdose but think of how cool you will feel?
Friend 1: I am so high, I am candyflipping right now off of a gel tab and a Tesla pill!

Me: He.. He was flatline flipping.

Officer: Holy shit cool

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."
