poop dickin' 

The act of obnoxiously yet leaisurely pounding one's fist into one's ass while holding the fist in a clenched fasion, whilst the individual is hunched over with their back arched all the while the audience procures enjoyment.

Jack was poop dickin' while the crowd enjoyed with uproarious laughter.

Poop deckin' 

The act of stealthily approaching a boat from another nautical vessel and pooping on the roof of the boat's cabin (i.e. the poop deck). It is customary to exclaim "You just got poop decked!" when leaving the scene.

After Jake successfully performed his first poop deckin', he exclaimed "You just got poop decked!"

Johnny poopdicking 

When a drunk girl explosively shits herself in and around your home and you proceed to rinse her off in your roommate's shower. In doing so, you become turned on and join the soiled girl in the poo-stained shower and proudly have sex with her.

(Insert name) had a crazy party last night and ended up Johnny poopdicking.
