How it's used
Originally referring to someone untrustworthy or backstabbing, the term has evolved to describe someone who is fickle or unreliable. It carries a strong, informal, and slightly derogatory tone that should be reserved for close friends or when expressing genuine frustration. Using it in professional or formal settings is highly inappropriate.

Common mistake
Do not use this to describe someone who is simply indecisive. It specifically implies that the person has made a commitment or stated an opinion and then reneged on it, causing inconvenience to others.
