It's all just a sign that children no longer seem to have a childhood as such. Much of the sexual innuendo/reference is probably picked up from those in the playground who mix with teenage peers. Unfortunately children do not say "Cor, what a swizz!" these days.

There was a rather amusing incident which happened a few years back when I was still teaching. The school I taught at had a very wide range of ethnic and social class backgrounds. There were two boys who came from the more well-heeled side of the catchment area one of whom decided on a bit of mischief -he went up to one of the girls in the playground and said "Alastair wants to shag you".

The lads obviously didn't know what the word meant, but had just said it because they knew it was probably rude. The girl promptly reported what had been said to the school caretaker, who was also the mid-day supervisor.

The caretaker gave both of the lads a suitably good dressing down and both came back into afternoon school looking suitably shame-faced.

The caretaker reported what had been said to me as I was the boys' class teacher. Apparently he had given them a lecture along the lines of:-

"Do you always go around saying that sort of thing?

"Do your parents talk like that?"

to which one of the lads relied:-

"Well I think I have heard my parents discussing shagging on occasions!"

This is not actually about homophobia, but I think it does show a bit about the playground dynamics which can produce the statements.
