When a group of men stand in a circle (similar to a circle jerk) and masturbate into a toilet. They then flush the toilet and walk away.

A group of males age 18-35 who religiously follow New Yawk's numbah one radio personality Mike Francesa not for his vast knowledge of sports, but for his ridiculous mannerisms and low tolerance for prank phone calls.
My boyfriend is out tonight with the ces-pool. Mike's appearing at Bar A again.
Boy there are a lot of prank callers today on WFAN. The ces-pool is alive and well.

When a guy ejaculates onto his stomach and the jizz slides down and wells in his belly button. Hence, gene "pool".
Guy 1: Dude, today I jerked it onto my chest and my jizz filled up my belly button!
Guy 2: I wish I could gene pool, but I have an inward belly button :/

You know how when you’re in the pool, and blowing water through a pool noodle, and someone turns the pool noodle backwards towards your face and it sprays you instead. But imagine the noodle is your dick and the girl you’re fucking turns you dick backwards towards you at the last second and sprays you with your own ejaculate.
