To “go silverback”: to fly into an intense and sudden rage which might involve contortions of the face, grimaces, a roar of anger and raised fists. After attacking and at least attempting to land a few punches, the rage recedes and the person often goes in a subdued and slightly embarrassed silence.

All I said was that I thought her sister was cute and she went totally silverback
