railing kill
A cliched maneuver of incapacitating adversaries in many action-based films by firing at a rival gunmen standing near a guard rail, to which they then flip over the structure (more often then not, clutching the entry wound before plummeting). Possibly first referenced in the Mystery Science Theater 3000 episode "Space Mutiny".
Damn, did you see how far the drop was after that railing kill?! The only thing that could've made that better was if he did a Wilhelm Scream!
