Fibber is derogatory slang for an FBI agent — a phonetic riff on the initialism 'FBI' that drips with distrust and contempt. It's the kind of nickname that signals you're not exactly a fan of federal law enforcement. Used in criminal, counterculture, and anti-establishment circles where calling someone a Fibber is basically calling them a snitch in a suit.
