zijn hoofd is ontploft?

"His head has exploded?" Translation: There is the image of a man appearing stunned or overwhelmed, his eyes wide and mouth agape in surprise. His hair stands on end, as if electric currents are coursing through it. Beads of sweat trickle down his forehead, and his face is flushed red from the stress or shock. His hands are up, fingers splayed out as if trying to fend off something invisible.
