EBS is short for Exploding Bowel Syndrome. EBS is a condition where your body builds up so much back pressure due to constipation, usually after eating mass loads of theater pop corn. Upon the release of this pressure, what ever is in the way (bottom of toilet, ground, significant other) is significantly harmed by the force at which fecal matter is expeled from the orrifice from which it originates.
Dick had such a bad case of EBS, the building maientance department had to replace the toilet in the mens restroom.
