What is the definition of Preceding Fluid?

A 'preceding fluid' is like the unsung hero of the body's circulatory system, but instead of being a fancy cocktail you sip on, it's the stuff that flows beneath our skin, preparing for the next big event or, in some bizarre cases, taking a sip from our next big adventure. It's the unsung hero of our body's survival, quietly waiting for the next action to happen.

Here's a darkly humorous example sentence: "The preceding fluid was so thirsty, it decided to take a sip of the next person's unspoken, existential dread."
