Sheptagon is a slang word for a heptadecagon, a seventeen sided shape. Thank me later. Some people also call it heptakaidecagon because why shouldn’t you add three unnecessary letters in the middle of the word?

Spentagon 

A term for the Pentagon, reflecting its incompetent spending of taxpayers money. The Spentagon continually demands more and more taxpayers money even though it cannot account for 25% of its budget.
Thus, the "Spentagon" is the very embodiment of "Big Government", eagerly supported by conservatives who claim to be against big government.
"Republicans love to criticise any flaws in social welfare and health spending, but they turn a blind eye to the Spentagon's losing trillions of dollars of taxpayers money and enormous waste."
