G.B.U.M
The most muscular guy in the world. Like a superhero who only fights in the gym and eats pizza for breakfast.
My gym buddy is a G. B. U. M. He can lift a car and still do 100 push-ups.
My uncle’s G. B. U. M. is so big, he wears a hat for his head.
The G. B. U. M. at the park bench eats 5 burgers and still flexes.
