What Does ‘stoolie definition’ Mean?
The stoolie definition refers to a person who informs on others to the police or another authority, usually about wrongdoing. In everyday speech, a stoolie is often thought of as a snitch or rat, someone who betrays a group by passing along information.
The term is informal and carries a negative tone most of the time, though in legal contexts the person described by the stoolie definition might be called a cooperating witness or confidential informant, which sound more neutral and technical.
Etymology and Origin of ‘stoolie definition’
To understand the stoolie definition you have to look back at the older phrase stool pigeon. That image of a pigeon tied to a stool or used as a decoy dates to the 19th century and landed in American slang as a word for someone who lures or betrays others.
Over time stool pigeon shortened to stoolie in informal speech. The stoolie definition kept the sense of betrayal, but the phrasing became more casual and portable, showing up in police talk, newspapers, and crime fiction. For a deeper etymological note see the stool pigeon entry on Wikipedia.
