had someone's back

Offered loyal protection

To have had someone's back is to have supported or protected them, especially during difficulty or conflict.

The phrase implies loyalty and readiness to defend: She had my back when the boss tried to blame me for the mistake.

Having someone's back suggests watching out for threats they can't see themselves—like a partner covering your blind spot.
