What is the definition of Selection Fluid?

Ah, the selection fluid - a fancy term for the stuff that makes sure you pick the perfect match from the vast ocean of options. It's like a personal matchmaker, but instead of recommending a movie, it recommends you over someone who might actually make you laugh and not just cry. Picture this: "In the quest to find your soulmate, I decided selection fluid was the heroine. 'Oh, look at me! This person is my perfect match - they can make me laugh even when I'm trying to take themselves seriously!'"

Now, here's a sentence that takes the concept to a darker level: "After years of dating in selection fluid, I finally found someone who could laugh at my terrible cooking and make me laugh at my terrible life choices."
