While an enemy sleeps, you hook up a sex swing above him or her. You climb into the swing and twist up the cords. As the swing untwists, you shit on your enemy's face. The untwisting of the swing causes your shit to curl into the form of a funnel, which makes you a human tornado. The OKC Steamer is also known as the Oklahoma Shitty.
Randy, the asshole, is due for an OKC Steamer!
