preposterous

To a vegetarian, the idea of eating a 52-ounce T-bone steak would seem preposterous — absolutely absurd.

When the word preposterous was first used, it meant reversing the normal order of things — putting what was last first, and vice versa. Imagine putting on your underwear over your pants and you'll see that there's a kind of absurdity in something that's backwards, which is why preposterous came to mean "ridiculous." The word is often used as part of an exclamation: a chef who is asked to cook with nothing but jelly beans might exclaim, "That's preposterous!"
