grown some balls

Found one's nerve

To have grown some balls is to have developed courage or assertiveness where it was previously lacking.

The phrase implies someone has overcome timidity to stand up for themselves or take bold action.

Vulgar but common: Finally grew some balls and asked for a raise.

The underlying metaphor equates testicles with masculine bravery.
