preposterous

Beyond all reason

Preposterous describes something so absurd or contrary to reason that it deserves ridicule.

The word carries more force than merely wrong—it suggests the claim or idea inverts common sense: The notion that the earth is flat is preposterous.

A preposterous demand, preposterous excuse, or preposterous price defies reasonable expectations.
