Slang for alcohol induced blackouts. Like a fuse in ones drinking circuit, it's a connection that can blow out unexpectedly when your personal tolerance maxes out while binge drinking. Unlike a circuit breaker, this cannot be reset. Total black out until you wake up, and you'll remember nothing.
I thought 3 beers an hour was fine, until my booze fuse blew out and it was lights out. I can't remember anything
