fistagon 

Term coined by Zack De La Rocha of Rage Against The Machine. Used to describe the iron-fisted Pentagon.

Terror rains drenchin', quenchin the thrist of power dons.
That five sided fist-a-gon.

Was it cast for the mass who burn and toil?
Or for the vultures who thirst for blood and oil?
A spectacle monopolized
They hold the reins and stole your eyes
The fistagons bullets and bombs
Who stuff the banks
Who staff the party ranks
