Often referred to as a poo caused by the unnecessary forcing of a fart, shart can also be used to describe a piece of art that one does not find appealing to their eyes/eye. "Shart" in this case is formed by the combination of the adjective "shitty" and the noun "art", which together create: "shitty art".
When Rick came across the popular piece of modern art, he gave his personal opinion on it "What makes this good? Really!? This is just shart! Plain and simple!"

An explosion like bowel movement. When one shits and farts at the same time. Can become huge problem if done on accident. If done on toilet, shit explodes and splashes water all over your ass.
The second I sat on the crapper, shit exploded out of me like a nuclear bomb. That was the biggest shart ever!
