The king hippopotamus. He runs the beach. The other hippos can't even go to sleep until Beachmaster does first. Now and then a younger hippo will challenge Beachmaster to a fight. If the challenger wins he becomes the new Beachmaster. However Beachmaster always wins. After victory Beachmaster will fornicate with a woman of his choosing. His favorite pastime is eating sausages from the sausage tree, which blossoms once a year. He is also very protective of his fellow hippos. When a hippo dies, Beachmaster will protect the corpse from hyennas, lions, crocodiles, or whatever. However if he's hungry he will eat it himself. The bottom line is that Beachmaster is the shit.
2. (In science fiction) A member of the fifth caste of the Beanoid species, a race of giant sentient bipedal extraterrestrial bean beings. Beanmasters form a ruling elite over the other castes that make up the bulk of the Beanoid population and their directions shape and steer the course the Beanoid Empire takes in its dealings with other sentient species.
All hail Beanmaster Charles- Supreme Master of The Beans!
"… And so it came to pass in the 5,988th year of the Galactic Era that the Beanmasters united the quarreling factions of the Beanoids, and set them on the path to forging what would in time become the formidable Beanoid Empire: the Federation's direst foe."
