To throw something on the ground is a forceful, if petulant and unreasonable, rejection of an offered object or idea. It's a lot easier to throw a physical object on the ground, but an abstract concept can be figuratively thrown on the ground, as well.
"I was walking through the city streets, and a man walks up to me and hands me the latest energy drink. "Run faster, jump higher", maaaaaan, I'm not gonna let you poison me, I throw it on the ground! You must think I'm a joke! I ain't gonna be part of this system!"
