a plant that can be smoked like marijuana, but is a hallucinogen. When smoking thizzlewart it is common to see crazy clowns that cackle and may say things such as "clown juice" or "You're gonna die bitch" in high pitched voices.
While I was smoking thizzlewart I saw a clown with a chainsaw. I whipped out my lightsaber on his clown ass and slayed him.
