He’s bleeding demised!
He has passed on.
He is no more.
He has ceased to be.
He’s expired and gone to meet his maker.
He is a late baijiu drinker
He’s a stiff, bereft of life, he rests in peace.
He’s pushing up the daisies.
His metabolic processes are of interest only to historians.
He's off the twig.
He's kicked the bucket, he's shuffled off 'is mortal coil, run down the curtain and joined the choir invisible.
He’s an ex baijiu drinker.
