Definition

A 19th-century New York term for a snitch or informer, because apparently even Victorian-era gangsters needed adorable euphemisms for rats. The word predates "snitch" and "narc" by decades, proving that every generation has needed creative ways to describe the guy who can't keep his mouth shut. Historical trash-talking at its finest.

Example Usage

"Don't tell Tommy anything sensitive—he's a total pigeon who'll go straight to the boss."
