MBS (Myles Bowel Syndrome) is a condition effecting the human digestive system, also known as, "I would rather have a shit than do any work today"syndrome. Common symptoms include the conscience requirement to take a shit at an hourly rate, and a near forced shitting commitment at the sight of a bathroom or portable toilet. It should be noted that a person suffering from the condition rarely has to take a shit on a scheduled lunch or bathroom break.
