[Editors] British idiom?

[Debbie Levey]

My Chinese houseguest relies heavily on an electronic translator 
device which seems to be programmed for British English, since it's 
full of words which I've learned from reading the Guardian  Weekly 
(toff, gormless). Yesterday we reviewed expressions using "soup" and 
it listed "soup and nuts" for what we'd call "tails" (men's formal 
clothing). Are you familiar with this term? I'd never heard it before.
