look up any word, like blumpkin:
A sex act in which the male wraps his penis in bacon, slathers it with beans, and proceeds to have sex with his preferred sexual partner. Upon reaching climax, the male will unload in his partner's mouth, forcing her to eat the Cowboy Casserole.
Partner - "I was hungry and horny at the same time the other day, so I decided let my boyfriend serve me a Cowboy Casserole."

Male - "I totally just gave my partner a Cowboy Casserole!"
