noun. an upper-decker (crapping in the upper tank of someone's toilet so that when they flush a stream of shit-water comes rushing in) that was left by someone who just ate a vegetarian meal.

in some locales a dominican sunrise requires that the vegetarian shit be deposited into a paper bag and then placed in the upper-toilet tank before flushing. this is also known as a vegetarian albanian christmas present upper-decker.

b: "what color is the water?"
a: "dewd, its shit-colored, but there's pine nuts and spinach all in there too."
b: "oh man, someone left you a dominican sunrise."
