warhead
n 1. A person who is in a state of delirium or confusion, distraction, after being struck by an epiphany
ex – “After finishing his quantum physics assignment, Fonzie really looked like a warhead today”
Origin: An English adoption of the Dutch word ‘warhoofd’, which has literally nothing to do with the word ‘war’ (as in ‘hostile conflict’), but all with the Dutch word of ‘war’, which means ‘confusion’ or ‘absent-mindedness’. I also liked the idea of the paradox: people struck by grand ideas are literally nuclear missiles, unstoppable until they’ve reached their goal. Or, until they go ballistic, I suppose.
