What's the meaning of 'spitballing'

Answer 1

I think here what it means is imagining or making up or suggesting (depends on the situation). Here you can see the list of possible thesaurus for that: http://thesaurus.reference.com/search?q=spitball

== == 1. A piece of paper chewed and shaped into a lump for use as a projectile.

2. Baseball An illegal pitch in which a foreign substance, such as saliva, is applied to the ball before it is thrown. Also called spitter. "Spitballing" in this context is a reference to definition #2. The purpose of applying a foreign substance such as saliva to the ball is to make the trajectory of the pitch unpredictable, and therefore difficult for the batter to hit. No one knows exactly what a spitball is going to do, not even the pitcher who threw it. "Spitballing", as for example in a business meeting, means throwing out an idea for consideration without great thought beforehand as to what the full ramifications of the idea might be.

Answer 2

"Spitballing" refers to casually suggesting ideas or brainstorming without much thought or planning. It is a way to generate new ideas quickly without worrying about details or feasibility.
