Apparently it was a 'she'.
Well I'll be...how times have changed.
As a young bloke I never... well very rarely ever heard women swear/cuss like that so assumed it was a bloke, based on the profanity and the testosterone levels present in the: "f**k you"
Yup, it seems to be a sad fact of life these days... that women can swear like navvies [road workers] and make a trooper blush with language more colourful than a satanic rainbow. I won't mention any names, but I know a couple of young females [one's a relative] whose language quite often leaves a lot to be desired, with f**k [or a derivative of it] usually being every second or third word used in every sentence.
For example, last year I asked one of them for directions to an old mate's place and got an abundance of f-words just to explain which streets I should take to get there. Now this mightn't be word for word exactly, but to get give an idea of why I ended up red-faced, it went very much along the lines of this:
"You know where the f**king post box is on f**king Alice Street, well you turn f**king left after that and keep fucking going down there 'til you f**king come to a set of f**king Traffic lights, where you turn f**king right into f**king, f**king... um, what's it's f**king name... f**king William Street and keep f**king going 'til you reach a f**king T-junction.. turn f**king left there and the f**king house is f**king fourth on the left just past the f**king shop."
Yeah, seriously, that was a young woman of 20, supposedly helping me find an old friend I'd lost touch with in the late 70's. What she mostly did, however, was confuse me more because I was taken aback by the excess of expletives and forgot the actual directions. Lucky for me, I knew the area and when I got to the shop [with "f**king this and f**king" that still ringing in my ears] I asked the owner [who turned out to be another old 70's mate] if he knew which house my other old mate lived in.... we all got together... happy ending.... I think... done gone and moved again, before I could tell him, didn't I.
