Informant: I’m from Oklahoma, and back home at football games, we always chant, “Kill, kill, blood makes the grass grow” whenever we’re winning or, like, about to make a big play.

Me: Like at professional games?

Informant: No, mostly at high school ones. And some college games.

The informant is a student at the University of Southern California and loves to attend and participate in sporting events.

This chant, in the context of football games, seems to mean that a brutal victory over an opponent will serve to make the field look better during the next game. However, variations of the chant also seem to be associated with the US military; it receives a nod in the title of author Johnny Rico’s memoir—and account of the year he spent fighting the Taliban in Afghanistan—Blood Makes the Grass Grow Green: A Year in the Desert with Team America. Another version of this chant appears in the 1987 war film Full Metal Jacket. The Sergeant asks, “What do we do for a living?” To which the platoon replies, “Kill, kill, kill!” The Sergeant continues with, “What makes the grass grow?” And his men reply, “Blood, blood, blood!”
