A SCatty rAH. Interesting hybrid exhibiting both scat and rah characteristics. Generally female. Notable features include (but not exclusive to): private education, southern English (non) accent (generally from one of the home counties), excessive fake tan, nose stud, bleached blonde hair and the subtle but very real smell of sex. There's a certain irony in the fact that Scahs will often spend vast sums of money in a bid to look like they live below the poverty line.
Trying to picture a Scah? Imagine a cross between Jodie Marsh and Keira Knightley. Or picture, if you will, the lesbian love child of Britney Spears and Joanna Lumley.
