A very popular menu item at Taco Bell. It includes nachos, cheese, bean dip, taco meat, lettuce, tomatoes. In other words a perfect mixture of a bunch of stuff that makes the average person crap themselves.
Hey Jason, you haven't had diarrhea in awhile... wanna go to Taco Bell and indulge in an Nachos BellGrande?
