Cotch (adj, v n)
Means: To do as little as possible with the aim of relaxation, or the actual venues for such inaction.
Usage: "I'm going to cotch round Gary's, Mum""There's a good cotch behind the playground"
In the Sixties it was "chilling", in the Nineties it was "hanging out", but every generation needs its own word to convey that base need of the young to waste time doing absolutely nothing on street corners and in random living rooms with their friends. As with many Yoofspeak entries, cotch derives from Jamaican patois, originally meaning to prop something up or rest somewhere. But this term is thought to derive from the French "se coucher", meaning to lie down (and considering much cotching is done on parents' couches around the country, it seems rather appropriate).
