Stomp

I was taught a new game tonight. It is the best stress reliever to date.
For example, this is what is says on one of the cards:

I shall stomp upon all who oppose me.
The stomping shall be swift.
The stomping shall be painful.
And I shall show no mercy
in all of my stomping.
Amen.

Does anyone know which game this is? (And no, you who taught me the game, cannot say.)
