A time when one feels it most polite to retire to a quiet space for a half hour slumber.
A short rejuvenating snooze.
Corporal: "Sir, the Germans are advancing on our front lines as we speak"
Captain: "How long do we have, old boy?"
Corporal: "Just under an hour, sir"
Captain: "Not to worry, my good man, Ill still have time for A Gentleman's Half Hour in that case, before the battle"
A really horrible situation.
A situation where you are being fucked over.
Too bad to be true.
A thrashing.
"God, I feel like a Man City v Watford"
"That was an absolute Man City v Watford"
