Some idioms I know of and think are quite quirky, are... "Gone for a Burton", this was thought to have originated in the UK during WWII amongst the air force troops and was used to indicate that someone had died in action. "Pop your clogs", if I'm not mistaken, in the Victorian times 'pop' meant 'pawn'. And a working man who knows he is close to death may sell or pawn his clothes and clogs(which would have been he's most expensive, valuable possession), to pay for his funeral. "Tango Uniform", This is to do with the phonetic alphabet and means 'Tits Up'. Its another phrase that originated with air force troops. It can be applied to people, animals and machinery that are broken, dead or out of commission.
