Diarrhea consisting only of pure fecal liquid with no solid feces contained within it. When expelled from the colon, the contraction of the anal sphincter will focus the diarrhea into an extremely narrow stream. The resulting laser beam can be focused in a specific direction with a distance proportional to the aperture of the sphincter. The color of the beam will vary depending on its source, from a neon yellow to a burnt orange.
Sally misfired her hershey laser in my bathroom last night. Now there's a hole in my toilet seat and a line of diarrhea running halfway up the wall!
