Bolt upright ⚡🧍

Meaning

To suddenly sit or stand in an erect position, often due to surprise or alarm.

Origin

Imagine a terrified horse, its muscles tensed, suddenly rearing up or 'bolting' from a perceived threat. This image of sudden, rigid motion, like a lightning bolt striking, inspired the phrase. When a person is startled awake or experiences a shock, their body can react with a similar abrupt, stiff posture, hence becoming 'bolt upright'.
