My siblings will understand this but I was not sure if it was purely a family expression or one that was used by people in general.
We have had a bit of inclement weather here recently and rather than being stuck indoors I suggested that we go for a bit of a charlie. It got me thinking about where the expression had originated as it was used in my family but it was not an expression my husband had been familiar with before he met me.
I did a bit of a search on the Internet under origins of sayings but couldn’t find anything there so I thought it might have been an expression associated with the Air Force, maybe something to do with the call sign alphabet but that didn’t seem to fit the bill either.
Eventually I thought it might be Cockney rhyming slang so did a search for that and sure enough, going for a charlie is Cockney for going for a ride, ( as in Charlie Pride). Here is the link to the Cockney Rhyming Slang.
