blowing one's top

Erupting in anger

Blowing one's top is losing one's temper suddenly and explosively.

The image is of pressure building until it bursts through the lid: When he saw the dent in his car, he blew his top.

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