What is the definition of Johnny Fluid?

"Johnny Fluid" is like the ultimate over-the-top superhero sidekick - a watery, chaotic, and utterly unpredictable entity. It's the name of a substance so viscous, it could potentially drown a submarine if left in its current state. But hey, let's keep it light-hearted, so here's an unsettling example: "I decided to channel Johnny Fluid and decided it was time to inject my existential dread into the pool, leaving behind a cloud of murky, philosophical angst that probably killed a few unsuspecting fish."
