art bum 

A person who is on the edge of doing art work, be it writing, acting, playing music or what have you. Although this person thinks about being artsy and doing art all the time, he or she rarely does it.

That art bum thinks he'll be the next picasso, but all he does is daydream.

bum-art 

Using your shit, and your bum cheeks to create beautiful shapes.

The most common artworks are beautiful Butterflies.

To create these works of art all you need to do is to push a relatively long turd, but before you cut the turtle, you need to stand up straight and mash your bum cheeks together.
This traps the turd between your bum cheeks and forms symmetrical Wing like shapes on both sides.

To see your work of art all you do is bend over in front of a mirror, spread your cheeks and enjoy your art!!

Son - Hey mom, you should have seen the beautiful butterfly i made at school today.
Mom - oh thats nice, why didn't you bring it home to show me?
Son - because all the other kids complained that i stink too much!!!
Mom - What do you mean?
Son - Its BUM-ART mom.
