You guys won’t believe it! I finally pulled off the 180 Splash Downtoday! It felt so good!
The area around the base of the urinal or toilet whereupon piss splashes whilst a person urinates. Not to be confused with 'splash zones' around swimming pools or at water parks.
"Honey would you please move your bunny slippers? They're in my splashzone."
