working the valves

When a man has just pulled up to a urinal in a public restroom and has a gas bubble drop to the back gate at the same time as the flow is about to start. At this moment, a friend walks in and calls you out by name. Now your identity is revealed to others that are in the stalls. With this happening, you can no longer let the brown cloud come flapping out. The only thing you can do is limit the flow with enough squeeze on the urethra that didn’ doesn’t compromise the rectum seal.

Fuck man, my boss walked in to bathroom right when I pulled up to the urinal. A gas bubble dropped and I was working the valves to save myself from an embarrassing fart.
