Normally used in reference to bath water. In it's natural environment, bath water is "clean", normally only dirty if your bathtub is dirty itself. But once a body is submerged, often just the lower half of said body, organisms and bacteria transition to the bathwater. Mostly unseen to the human eye, these organisms and bacteria spread throughout the bathwater in the steady metamorphosis into ass water.

after trying for 13 minutes, john finally squeezed out the last terd. Sadly, the terd was heavy and produced superfluous ass water.

Alternate name for Booty Sweat, and energy drink from the movie Tropic Thunder. ALSO, the water that splashes on your ass when you're taking a poop. Very annoying, often resulting in the need for extra toilet paper usage.

Tennessee delicacy served in only the finest sit-down establishments. A semi clear, semi-odorless, semi-tasteless drink served over ice.

the terrible coffee offered in hotel rooms, especially once prepared. this coffee tastes especially watered down and resembles ass more so than coffee.
wow, the coffee from this marriot that were staying in for our class trip to boston that tastes like asswater.
