Maybe this definition deformed the literal meaning of this sentence if there ever was anything literal about anything.

This definition is derived from the elemental analysis of the sentence. To be more exact, the first part of the sentence, "Say it," derives from the necessity of focus in the thought, while the second part, ", don't spray it." depicts the actual state of the thought.

As a conclusion, when someone says this to you, it means u went to far with your point that he lost track of it, or he is at a point of loosing it.
"Say it, don't spray it."
The above definition is clear example for example.
