Flatliner President 

An increasingly popular nickname for the 45th POTUS as he nears the end of his one and only term.

Thanks in great part to his mismanagement of the pandemic, the Grabber in Chief will from now on be known as the Flatliner President.

flatline 

1. (n) A period after quitting masturbation/porn addiction when libido is severely decreased, orgasms are hard to reach and erectile dysfunction is observed in men. Often anxiety-inducing and a common reason to fall back into habitual porn consumption (as a "test" to see if the body still responds). Total duration can vary from a couple of days to over a month; however, they typically go away with time.

2. (v) To experience a flatline.

1. Curses! I just got a booty call from Ann, but I'm in the middle of a flatline, what if I can't perform?

2. "Why didn't you come over to my apartment last night?" "I'd have loved to, but I'm trying to abstain from sexual stimulation and now I'm flatlining." "What, and your fingers fell of as well?"

Flassing 

Treating a girl like shit in order to manipulate her into finding you attractive, at least for a day or two. You completely disregard the females feelings to control her.

Sohil, you were flassing too hard back there, I thought she was going to slap the shit out of you.
