spitball

In its most literal sense, a spitball is a little ball of chewed paper, often made from a scrap of notebook paper, that is blown from the mouth through a straw or flicked by hand. It is a classic school prank and is strongly linked with the image of a mischievous or disruptive student.

Beyond the schoolyard, the word also has a place in baseball history. In baseball, a spitball is a pitch in which the ball has been changed with saliva or another substance so it moves in an unusual way. Because this gave pitchers an unfair advantage, the pitch was banned by Major League Baseball in 1920.

Today, you are very likely to hear the word in meetings and casual conversation. As a verb, to spitball means to suggest ideas freely, without worrying whether they are perfect. It often describes an informal brainstorming session where people are testing possibilities. For example: "We do not have a strategy yet; we are just spitballing a few marketing ideas."

So the word can point to three main things: a wet paper pellet used as a prank, an illegal baseball pitch, or an informal idea tossed out for discussion. In every sense, it suggests something quick, rough, and not fully polished.
