A pooch pizzle is normally when you lean over and take a piss on something in the fashion of a male dog.
I decided to troll the other people in the urinal, so I leaned over, unzipped my pants, and took a big ol' pooch pizzle. The guy in the stall next to me... let's just say "he was damn pissed!"
One time when I was 8, I was curious what it'd feel like to be a dog. I told my mom I'd go outside to pretend something new. 10 or so minutes later, she caught me pooch pizzling on our fence. That put an abrupt end to my childhood.

Genson: What is this new maneuver?
Renard: We will call it, The Circular Pooch Cooch!
