Yah

[Sarah]

An arrogant upper/upper-middle class lady or gent, typically a student in an otherwise charming Scottish town or city.
Girls = flowing blonde hair, pink pashmina, ironically kitsch little bag, astounding ignorance, charming high-pitched giggle.
Guys = floppy birds nest-esque hair, woollen jumpers, suspiciously tanned, exceptionally loud and annoying voice which will usually be spouting some kind of patronising ex-public-schoolboy wit.
Possibly originating from their judicious use of yah, darling, yah in general conversation.
