Often referred to as a Bad B M. It's the process of running to the toilet, taking a monstrous dump and missing the toilet bowl. The term originated in England in the 14th century when there was a nobleman named Sir Brandon who was noted for taking monstrous dumps in public places for all to see.
Man, I just ran to the can and dropped a Brandon. If the janitor discovers who did it, he’ll kill me.
