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.
