Defined as: Noun: What your ass turns into after partaking in a fast food lunch. It is also another way of saying diarrhea. The end result is your ass spackling a toilet wall with shit. This term is coined after the famous hand operated kitchen utensil sold on TV in the 80's which "shot" salad from a small orifice.
Damn that supposedly healthy sandwich I just ate made me run to the bathroom for a salad shooter experience.
