Men of Reddit - how do you shake after you pee.

So for context, I'm a guy, and this question came about after I was at a urinal standing next to a small guy, and when he finished I could see him putting his whole shoulder into the shake, which made me immediately think "he must have a huge cock". Then I thought what if he didn't, what if that was just an unknown power move I never knew about. My whole life I've pinched my little squid like I'm wielding chopsticks and shaking the excess broth from my noodles. This guy shaked it like he was unravelling a fire hose. I'm so rattled. I've been trying to practice the fire hose technique but I feel like I'm not doing it justice. How does everyone else shake at the urinal? Am i the only one who didn't know about this, is it an actual thing?
