Have someone's back
Meaning
To support and protect someone, especially in a difficult situation.
Origin
The phrase "have someone's back" vividly originates from the crucial need for vigilance in combat. In military formations or dangerous encounters, an attack from behind is often the most deadly. To "have someone's back" meant literally watching over their rear, guarding them from unseen threats while they focused forward. This vital act of physical protection quickly transformed into a powerful metaphor for providing unwavering support, loyalty, and advocacy, ensuring a comrade's safety and well-being even when they can't defend themselves.
Examples
- Don't worry about speaking up in the meeting; I will have your back if things get tough.
- A good team always knows they can rely on their teammates to have each other's backs.
