I have never had an issue with swear words and have always explained to my children that some people can be offended by certain (swear) words, so don't use them outside the home unless you want the possibility of people judging you harshly. Obviously I say it in Kidsspeak. To me, unless swear words are aimed at me aggressively, they are just harmless sounds. Actually, I lie a bit, I do sometimes use them for impact to stress a point of passion.
Last Friday night, my whole family wandered into the off-licence after a street walk so that Andy Chap could buy himself a bottle of posh cider. Recently he's become a bit of an alcohol snob. While in the shop, a couple of women entered that were clearly on their way to some drunken fun. They asked the lad behind the counter that was surrounded by 'no ID no sale signs' (that I had been staring at because I felt I should ask him for some ID - he looked twelve like all the policemen) for a particular type of beer. He pointed to a shelf and they grabbed some. The server then informed the women that there were refrigerated ones and asked if they would prefer them to which one of the women, very aware of my children replied,
"Oh yes, that would be the canine reproductive organs."
Forgive me if this a commonly used phrase in these circumstances. I have certainly never heard of it before and found it very funny and laughed appreciatively.
As we left the off-licence, my daughter asked what canine reproductive organs were. I said within earshot of the women, it means, 'the dog's boll*cks'.
