What it means
Proper old-school way to say you're completely knackered, like your body’s flashing low-battery and even chatting feels like cardio. It comes from the older verb fag, meaning to toil or wear yourself out, not the US slur. Bit dated now, and it can sound dodgy abroad, but you’ll still hear it from people who’ve been run ragged. Usually said after a long shift or a mad week.
Usage examples
"I’m fagged out, mate. Twelve-hour shift, Tube was rammed, and I’ve still got washing up waiting. Stick the kettle on, I’m done."
"After moving boxes up four flights all afternoon, I was fagged out before we even started on the furniture."
"The kids are fagged out after the school trip, both asleep before we'd left the car park."
