Leveller, what about:

not-folk
old-folk
old-folk(s)
this-folk
that-folk
shit-folk
not-your-kind-of-folk

I'll-get-me-cloak-folk

p.s. loved your Sir Patrick Spens on the 'nice but dim' thread yesterday.

Just waiting for the responses from the people who think 'they' refers to them (it doesn't by the way).
