Congregating wherever aged proto-dance acts play at summer festivals, and typified by the "Dog-on-a-string"; Crusties are aging psychadelia fans, acid burn outs, or just vegans who don't like to wash their hair (or their dog).
Stumbled into the Ozric Tenticles tent, tripped over a dog on a string and had mexican mushrooms shoved up my jumper by a unwashed hippy. I love the smell of crusties in the summer.
