i don't know about the sterotype but i have a good idea where stoned or stoner comes from... because the sterotype for us is that we sit there and do absolutely nothing all day... like a stone... as for sterotypes, maybe 20, 30 years ago sterotypes worked.. i can't say for sure as i wasn't alive back then, but these days, all the cultures mixed there is not even one sterotype that holds true to everyone (or even most) except that we live and we die, which isn't really a sterotype, just more of a fact...
