I've been muttering darkly about the grockles who think it's OK to park their Range Rover in a passing place on single track roads just because the sun has come out and they're down for the weekend. Weekend surfers in their VW sports vans are just as bad and need lessons in reversing. Non locals and tourists are grockles or emmets to us, but what do you call them if you live in the Lake District, New Forest or Norfolk?
