ice turd 

ice turds:

What becomes a big nasty blackish hunk of frozen street slush, and will attach to the back of a wheel well, only to drop in inopportune places, and look all nasty-assty.

Boss; Look, you're in charge of the parking clean up. I want all those ice turds cleaned up and off the premisses by closing time or you are fired!

Lackey; Damn man, them rustlucks is froz down like Santa's balls.

Boss; Well I nearly broke my toe on one just now, and if you don't get them gone right now you will be thawing Santa's balls in your next line of work!

Iceturd 

A large volume of human excrement that 'fills the pan' and pokes up out of the water. So named as it resembles a dark chocolate version of the large bodies of ice that scatter the oceans in the polar regions. The majority of its bulk being underwater, a solid lump protrudes into clear air space and fills the room with its noxious odor.

"Dude, after that stack of wings and pizza last night, I just laid down an iceturd."

"Excuse me your honor, I'm unable to address parliament this afternoon, I have a desperate need to launch an iceturd upon the high seas." (taken from British prime minister Tony Blair's private diaries)
