Midnight Mexican bird's nest
The act of pooping on the roof of an unsuspecting person's car late at night, preferably close to the edge of the drivers side door then sticking yellow Marshmallow baby chicks into it, resulting in subjecting the car's owner to the sight before they enter it the next morning.
Man, that smelly-ass freeloader has been getting on my last nerve, maybe a midnight Mexican bird's nest would make him get the point.
