A worst-case scenario that's far worse than any realistic scenario.
"What's the worst thing that could happen?"It's useful to have a worst-case scenario. When you're deciding tactics, or investing, or anything else, it can be helpful to judge your risk in part by figuring out what your worst possible loss could be. However, some characters take this too far. A worst-case scenario could be that, if Bob invests a certain way, he loses his investment. A ridiculous case is that Bob's investment is used to finance a nanorobot swarm that consumes all matter in the universe. A worst-case scenario in planning a driving route might be getting lost, or perhaps breaking down on some back road. A ridiculous-case scenario could be driving into a wormhole that teleports the driver to the middle of the sun. Some characters will try to justify this by explaining that they are just interpreting 'worst' literally. Any attempts to confine the scenarios to those that have at least a small probability of actually happening will be invariably brushed off. A subversion might be a worst-case scenario that's actually not all that bad. Rolling Updates Examples:
"Our beta product could turn into an evil robot that annihilates the galaxy."
"Apparently, I don't know what 'worst' means."
