One person cannot be a steez, so the term Steez Hat must be used. A steez hat can range from someone you completely hate to someone that won't get you a pepsi. It can also be used to describe your cat if he/shedrops a deuce on your carpet.
"We didn't even find any weapons of mass destruction. Bush is such a Steez Hat."
"Mallory, quit being a Steez Hat and get me a sandwich."
