snitch

A "snitch" is usually someone you do not want on your side. It is slang for a person who tells authorities or other people in charge about what someone else did wrong, often in a secret or disloyal way. It can also be a verb: to "snitch" means to tell on someone. Think of a kid who runs to a parent or teacher to report what another kid did; that kid may be called a snitch. The word has a strong negative feeling. People use it in crime stories, at school, or in any situation where people think loyalty matters. You might hear, "Don't snitch on me," or "Don't be a snitch."

The word "snitch" carries a lot of weight and is almost always negative. As a noun, it refers to a person who tells on others, especially by reporting their bad behavior or illegal acts to authorities. As a verb, it means to do that reporting: to tell on someone. While "informant" can sound neutral, "snitch" usually suggests betrayal, broken trust, or telling for selfish reasons, such as trying to avoid trouble yourself.

The word has strong ties to crime and prison culture, where staying silent is often treated like a rule. In that world, a snitch is someone who cooperates with the police or gives information about other people. But the word is also common in everyday life. Kids may use it for someone who tattles to a teacher, and adults may use it for a person who reveals secrets, reports rule-breaking, or exposes someone else's actions to people in charge.

Context matters. Calling someone a "snitch" is rarely a compliment; it is usually an accusation of disloyalty. You might hear, "He snitched on his brother for eating the last cookie," or "The police relied on a snitch to break up the drug ring." Sometimes the act is morally right, but the word itself still sounds harsh because it focuses on the social cost of telling. It is a word about trust, loyalty, silence, and the risk that comes with speaking up.
