blow one's top

Explode in anger

To blow one's top is to lose one's temper suddenly and explosively: When he saw the dent in his car, he blew his top.

The image suggests pressure building until it erupts violently, like a volcano or overheated container.

The phrase is informal and slightly dated, with blow a fuse and lose it serving as near equivalents.
