What is the definition of Estimated Fluid?

An 'estimated fluid' is like the cosmic equivalent of a pie that's been thrown into the void, but instead of being thrown, it's been calculated to fill up a bathtub. It's the fluid that comes into play when you're trying to figure out how much of a thing you need, but somehow it keeps changing its size like it's playing hide and seek with the laws of physics.

Here's an edgy example sentence: "After the team's epic loss, the coach estimated the fluid needed for the next game to be a sea of 'I don't know' and 'Maybe next time' because, you know, we've seen the universe play a trick on us."
