lost one's cool
Flew off handle
To lose one's cool is to become visibly angry, flustered, or upset after previously maintaining composure.
The phrase implies a breakdown of emotional control: She lost her cool when the third person interrupted her presentation.
Someone who keeps their cool stays calm under pressure; someone who loses it lets frustration or anger show.
