What does plunker mean?
A plunker is most commonly an informal, disparaging term for a baseball player who makes weak contact with the ball, often sending a low ground ball into the infield. The word can also refer more generally to a person or thing that is ineffective, disappointing, or capable only of tapping or lightly striking something. Its tone is distinctly dismissive rather than neutral, so it is more likely to appear in commentary, criticism, or conversation than in formal writing. The expression evokes the sound of a poorly timed or feeble hit: the batter may swing with apparent force, yet the result is feeble. Although the word can be understood in several contexts, its sporting sense is the one most likely to come to mind to North American readers.
A person who plays ineffectively, especially a baseball player who hits the ball weakly.
"The manager replaced the plunker with a player who could hit for power."
Informal and usually disparaging.
A person or device that plunks, taps, or plucks something.
"The small instrument was little more than a plunker for the strings."
Less common than the baseball sense and dependent on context.
Used when referring to multiple people who play ineffectively or make weak contact with the ball.
"The two plunkers were replaced before the end of the series."
In baseball slang, a plunker is a hitter whose weak contact can make a solid-looking bat swing produce an embarrassing result.

Where does plunker come from?
The word is a derivative of plunk, an English verb meaning to make a light, hollow sound or to place something with such a sound. Adding the suffix -er creates a noun denoting a person or thing associated with that action. In American baseball slang, the meaning developed toward a player who makes weak contact, while the broader sense of an ineffective person or thing became an occasional figurative extension.
