frighten the life out of someone

Petrify them utterly

To frighten the life out of someone is to terrify them completely, to scare them so badly they feel momentarily as if their heart might stop.

The expression emphasizes the intensity of the fright rather than any literal danger.

That horror movie frightened the life out of me.

Variants include scare the life out of and, more colorfully, scare the living daylights out of.
