Get the Fat Assmug. When a person is so large they generate a gravitational field. They are so heavy the ground around them cracks. They are covered in so much blubber that they need 2 lanes to swim in. They have so much mass that they are bigger than some of Jupiter's moons. They are so big blue whales hit on them when they go to the beach.
