loses one's cool
Flies off handle
To lose one's cool is to become visibly angry, flustered, or agitated after maintaining composure.
The phrase implies a breakdown of self-control: She kept her cool through most of the interview but lost it when they brought up her ex.
Cool here means calm self-possession, so losing it means that calm has slipped away.
