A line in the 1985 screen play, Full Metal Jacket, written by Stanley Kubrick.
Gunnery Sergeant Gerheim asks, "What do
we do for a living, ladies!" and the platoon
replies, "KILL! KILL! KILL!"

He then asks, "What makes the grass grow?"
and they reply "BLOOD! BLOOD! BLOOD!"

Chant used during bayonet drills for many army's, including the British.
What makes the grass grow?
Blood, blood, blood!
Who's Blood?
The Enemies!
Who's Enemie?
The Queens Enemies
