When I were a lad, to get to the chip shop at lunchtime from our grammar school you had to walk past the local comp. We never got much trouble from the lads but the girls were dangerous. They wore grey pullovers, white blouses, navy blue skirts but most relevantly black monkey boots (with white socks). They were all real Salford Slags and were all called Trehseh, Karron and Sharron and got help you if they accosted you for a chip and you gave the wrong answer because you usually got a kick in the shin with a monkey boot.
It actually became quite an in joke to run away from them where you would have stood your ground with the lads. Strange creatures.
