How it's used

Originally referring to a hardware cheat device for video games, the term evolved to describe someone who secretly reports others to authority figures for personal gain. It carries a strong negative connotation of disloyalty and untrustworthiness. Unlike a simple tattletale, a 金手指 often implies a calculated betrayal within a group or organization.

Common phrases

to act as a snitch

Common mistake

Do not confuse this with the literal meaning of a golden finger, as the metaphorical usage is almost exclusively about betrayal. Using it to describe someone who is simply pointing at something will cause confusion.
