Flailing Susan 

An advanced position in sexual intercourse involving one man and one woman. The woman, on top of the man, does the splits while hanging from something. The man lies on his back on a lazy-susan, inserts his erection into the woman, and starts to spin on the lazy-susan while remaining inside her.

STRETCH AND LUBRICATE PRIOR TO ATTEMPTING!

Caitlin: Wanna try the flailing susan tonight?!
Jason: Hell yeah, but let's use extra lube since I got really chaffed last time.

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?"
