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?"
