The quiet, understated version of exhaustion — you're not dramatically wrecked, but something in the background is definitely running on empty. Low key knackered is the tiredness you carry without broadcasting it, the kind that sits underneath a functional exterior while your eyes are slowly glazing over. It's used as a soft admission, usually dropped into conversation casually, that you're not quite right but you're not ready to make it anyone's problem either. Often signals the need for an early night without making it a whole thing.
Don't mind me, I'm low key knackered today but I'll survive — just don't expect wit until after coffee.
