Shadow Cocks can be hidden on a side mirror or behind the rear view mirror or openly displayed on the side or back windows. Multiple shadow cocks are usually applied. On a station wagon the hearse shadow cock can be applied where a matching cock is applied hearse style on opposing back windows.
D-Bag: WTF, why is there a huge cock on my back window?
D-bag's side kick: Uh... You got shadow cocked dude!
