I hadn't really. Lav is the only one I could think of but here in Britain (don't know about the rest of the world) 'lav' is a slang term for toilet though it's never done me any harm (
Lou --> 'loo' is also a slang term for toilet here).
I thought
Lally (or
Lallie) would be a good one, not for all the time use (like maybe
Bill or
Liz) but just for occasional use rather than having to use
Lavender all the time.
But according to the poll it seems to be a almost definite no :(
