moron dust

noun. The stuff of morons--especially when they get blowed up.

Real citation: "Even though the guy's a moral and practical idiot, I'll still feel sorry for him if and when an American bomb turns his stupid ass to moron dust."

Made-up citation: “If all the morons in the world were reduced to moron dust, that would be bad for anyone with allergies.”
