Behind these two booths was an enormous roller coaster, a phrase which here means “a series of small carts where people can sit and race up and down steep and frightening hills of tracks, for no discernible reason.”

A Series of Unfortunate Events: The Carnivorous Carnival – Lemony Snicket

When my workday is over, and I have closed my notebook, hidden my pen, and sawed holes in my rented canoe so that it cannot be found, I often like to spend the evening in conversation with my few surviving friends. Sometimes we discuss literature. Sometimes we discuss the people who are trying to destroy us, and if there is any hope of escaping from them. And sometimes we discuss frightening and troublesome animals that might be nearby, and this topic always leads to much disagreement over which part of a frightening and troublesome beast is the most frightening and troublesome. Some say the teeth of the beast, because teeth are used for eating children, and often their parents, and gnawing their bones. Some say the claws of the beast, because claws are used for ripping things to shreds. And some say the hair of the beast, because hair can make allergic people sneeze.

But I always insist that the most frightening part of any beast is its belly, for the simple reason that if you are seeing the belly of the beast it means you have already seen the teeth of the beast and the claws of the beast and even the hair of the beast, and now you are trapped and there is probably no hope for you. For this reason, the phrase “in the belly of the beast” has become an expression which means “inside some terrible place with little chance of escaping safely,” and it is not an expression one should look forward to using.
