9-12ing

9-12 represents the peak hours for jerking off, when most people are still awake and have alone time. 9-12ing is slang for jerking off, especially during the peak hours of 9 pm-12 am. Iterations of time periods can also be used to reference jerking off. The more absurd the times and time frames are, the more appalling the session is. Commonly used time periods include 1-3 (1 am-3 am), 12-12 (12 pm-12 am), 3-5 (3 am - 5 am), and more.

"It's 10:30 pm. There's only an hour and a half left to 9-12."
"I graduated from 9-12 five years ago. I'm much more of a 3-5 guy now."
"Why isn't he coming out tonight? He's probably 9-12ing in his room."
