Egyptian word derived from the ancient word bot-hous the slaves used at the time, roughly translating to Butt-Hole. This surname was given to the Egyptian slaves that carried a foul odor similar to that of a camel's "Butt-Hole". These "Butt-Hole's" were not asked by the slave masters to carry out any labor as to avoid the odor. This trait became desirable as one might imagine, and developed into a general laziness over several generations.
