What is the definition of Strictly Light Particles?

Ah, 'trictly light particles' - the cosmic equivalent of a bad pun, but way more fundamental! These aren't your ordinary, everyday particles. They're like cosmic ice cream cones, but instead of chocolate and sprinkles, they're made entirely of photons (light) and virtual particles (because, you know, what's life without a little ghostly fun?). They're so light they could theoretically slip through any window, including the one between your brain and your heart (unless you've got a superpowered vacuum cleaner - which would be a bit too much energy for those virtual pals).

Here's an edgy example sentence: "The cosmic 'trictly light particles' decided to sneak into my mind and start a virtual reality nightmare, complete with quantum versions of my favorite existentialist quotes." 🌌💫
