look up any word, like spook:
 
1.
One of the most intimidating weapons know to mankind.
"By god Jim! Is that a crap print on your cheek?"

"Yeah"

"It stinks! What happened?"

"Spock decided to bring a poosock to our bi-weekly senior officer pillow fight."

"I guess his sence of humor is returning."

2.
a sock that has been digested and pooped out and the sock is still intact.
a dog eats a sock then poops out the sock. thus making it a poo sock. it almost looks like a turd but you can tell that it is totally a sock caked in poo.
