Rusty Douglas

The act of taking a shitty, unwiped anus, and pressing it upon someone's house. Preferably on a window or a sliding glass door, leaving a brown, shitty kiss mark of someone's asshole on said surface.

"Man, someone left a rust Douglas on my neighbors window last night. Had the whole neighborhoods feathers ruffled."

"If you don't quit, someone is likely to give you a rusty douglas"
