When some unexpectedly kind of liquid sprinkles on your head/body, and you have to touch it with your hand and look at it to identify the liquid. This usually happens when it's not raining or when you're inside. The build-up to the reveal is always intense, yet 9/10 times it's still water. You always think it's birdshit or some kind of bodily fluid.
"I walked beneath a tree yesterday and got a mystery sprinkle. I thought it was birdshit but it turned out to be just water."

2. Bob- Come on! Let's take the subway!
Jim- What's wrong with you, man? The store's just around the corner.
Bob- I just want a dose of Mystery-wind.
