sqwkvfr,
Do you think everyone know's what....
means or
or
??
Perhaps we should recommend the London controllers to start using their local slang, When you've finished learning that don't forget the other local slang from Brum, Gordie-land, Scotland, the Welsh language, ETC ETC. and that's just the U.K. - next would be Europe and that wouldn't even be in English.
Did I know what
was before I read it on here ? Like hell I did. For all I knew he could have been talking about the colour of someone's tee-shirt.
