blow one's stack

Explode in anger

To blow one's stack is to lose one's temper suddenly and explosively.

The image is of steam building up pressure until it blows the top off: When he saw the dent in his car, he blew his stack.

The expression is informal and suggests an outburst that may be disproportionate to the provocation.
