And, to extend MtheGM's "Something·rude-all" is an odd English idiom for 'nothing': 'fuck-all, 'bugger-all', 'sod-all', 'bleed-all' — all mean 'nothing', idiomatically. Why, I have no idea, most of those expressions can have "-off" replacing the "-all"; all of them (except his last) mean "go away!!!!"

And, to extend his Sweet Fanny adams comment, when describing an infinitesimally small amount. the phrase I've heard for most of my life (and used by me only a couple of days ago) is "three fifths of five eighths of Sweet Fanny Adams". I'm indebted to MtheGM for giving added meaning to the phrase.

Cheers, Rowan
