losing one's cool
Temper getting away
Losing one's cool is becoming visibly angry, flustered, or emotionally unhinged after maintaining composure.
Cool here is the calm, collected demeanor someone projects under pressure.
The phrase implies a threshold crossed—control gives way to outburst: He lost his cool when they questioned his honesty.
The opposite is keeping one's cool.
