Shartworms 

When you have hot snakes and a small one leaks out as you are trying to pass gas.

Bro, I have to change my underwear before we go. I had some shartworms leak out just now

Shartwork 

When you release your bowels on the wall and make a beautiful work of art out of it.

Billy: What's with all this shit on the wall?
Jared: Get this through your head: this isn't just shit, this is some high quality shartwork.
Billy: This still looks like shit.

Shartwork 

When your poop forms into a beautiful image floating in the toilet.

I went for my morning poo and got up to see the Mona Lisa from my droppings. It was a wonderful piece of shartwork.
