Bullshit!
Sorry, I mean I believe your story but the only thing I know how to sign is "bullshit". I did know "gay" (as in homosexual*) but I've forgotten it -- which is a shame because I seem to recall it looked like some kind of pointing you could do to mates and they'd not think anything of it.

*Not knowing sign language I don't know whether "gay" as in happy and "gay" meaning homosexual are the same, or whether "homosexual" and "gay" are the same sign or not.

BSL
Isn't a 1:1 equivalence to English. It's more about the concept that is expressed by a particular sign. BSL is a completely separate language, which is as different to English as, say, Mandarin...

Yes, I know that.
I was taught "bullshit" in BSL by a colleague and the "gay" sign in a restaurant in Norway. I'm told they use BSL in Norway rather than anything local -- because it doesn't matter.
This is why I made an effort to explain the meaning of the word "gay" I was referring to and, also, why I mentioned I knew it may not be signed the same as "homosexual".

There is a Norweign sign language
with 2 dialects, but sign language users tend to be able to switch into almost any sign language quite easily, especially when they have experience of it, and the native language has borrowed or developed from another.
'gay' meaning happy has a different sign to 'gay' meaning 'homosexual'.
'gay' and 'homosexual' are the same sign but just performed in a more informal/formal way respectively. It all depends on the context really, and if you are talking about a man or a woman.

Thanks, the drunken conversation is coming back to me.
It could be the whole Nynorsk/Bokmal and other dialectal stuff that meant she knew and used British.
So, what is "gay", meaning homosexual, then? I think it's a bit like a "pointing two guns" gesture, for some reason...

The same page has the sign for lesbian too. Although I do both from the palm of the hand. Oo-er.

Oops! Sorry...
That sounded horribly patronising, didn't it? Beg your pardon, sir!

It's OK, you can't help it.
You're thumbs-up rocking on an open palm. Well, unless you are gay, in which case you're some sign I don't know which means "straight".
