What is the definition of Importantly Light Particles?

Importantly light particles are like cosmic cosmic breadcrumbs, floating around the universe with zero mass, just buzzing around like they're auditioning for a comedy sketch but with zero props. They're the kind of particles that would make a comedian roll their eyes and say, "That's one funny punchline!" But hey, in the grand scheme of things, they're also super-unsettling - because they're literally making the universe a little less serious and a lot more awkwardly comical.
