Distraction - pointing, looking scared and saying "what's that behind you?" so you can high-tail it or kick the hero in the bollo**s whilst they are looking around.
Chinny beard - the ominous stroking of the beard/moutache
gun sign - making a gun with your hands, pointing at the target and pretending to shoot them
dancing - instead of that stupid wiggle, do headbanging a la beavis and butthead
