The term haza was introduced by the character Frank Lopez in the film Scarface. Haza is a yiddish word for a pig, or a pig that doesn't fly straight. The term was later backfired onto Frank when Tony discovered that it was Frank who had attemted to assassinate him.
"You know what a haza is Frank?! A pig that don't fly straight, and neither do you!"
