Doing my usual cryptic crossword today I came across a clue "spare personal injury", "gxsx", a word I haven't heard in this context since my National Service days, 60 odd years ago. Does it bring back memories for others? Gash, I mean.
Gash in RM / RN normally means "rubbish" so to throw away rubbish is to ditch the gash. It can also mean spare or extra so a spare man with no job is a gash hand. Can be used to denigrate kit or people etc , such as " That is a gash car". ( Former RM ). We are coming towards Crimbo, the scran will be essence and we will have a hoofing time!
There is a book called Jackspeak. There are some subtle differences but mostly similarities between RM and RM . When I was in RM we would use terms to confuse other services such as referring to RAF as Crabair or in an Army barracks would sweep the deck etc etc
No - you are confusing the RM with the HLI . When they left Malta 45 Commando sent a request to the local forces radio - in 1957 - for "Their friends in the HLI" on their departure "Where Sheep May Safely Graze". The DJ did not, I suspect "get it". Hoofing in RM is " great" , threaders is exhausted , going ashore is going out, - plenty more!
