stab in the back

Betray a friend

To stab someone in the back is to betray them, especially while pretending friendship or loyalty: He stabbed me in the back by going to the boss with my idea.

A stab in the back is such a betrayal.

The image is of attacking someone from behind while they trust you enough to turn away.

A backstabber makes a habit of it.
