Cream of Mushroom

The curse of calamity; uttering the words "cream of mushroom" invokes a wrathful curse upon the world. Each time it is uttered, something bad happens to someone in the world.
Example 1

Guy 1: hey jackass, I'm gonna beat the shit out of you
Guy 2: cream of mushroom.
Guy 1 was then mauled to death by a bear in a gruesome manner.

Example 2

Guy 1: none can stop me now. I am the definition of godliness. Fall beneath me; cream of mushroom.

The world was then slowly ripped apart as the sky began to fall and magma charred the earth, leaving no survivors.
