rat fink

Despicable tattletale type

A rat fink is an informer or snitch—someone who betrays confidences or reports others' wrongdoing to authorities.

The term doubles down on contempt: both *rat* and *fink* independently mean informer.

The rat fink told the boss who started the rumor.

The phrase can also describe anyone considered despicable or untrustworthy.
