The small yet numerous particles of urine that are reflected back at you when you pee into a urinal/toilet bowl. This phenomena usually happens when too much force is exerted when trying to force the urine out, causing the pee to have such a high velocity that when it strikes the surface (either water or porcelian) it instantly atomizes and reflects back toward the direction where it originated from.
