"Ear stretching is a modification practiced by and originating from indigenous peoples. Tribes in various countries in Africa, Eurasia, Native American tribes and other indigenous lands have practiced the ritual of ear stretching for cultural, religious and traditional purposes. This is a ritual that has been practiced by people all over the world from ancient times. Bone, horn, wood, and stone were generally carved for ear stretching, but other organic materials that had the right shape naturally, from shells to teeth and claws, were also used."
Stretchers really did not become popular until the 21th century . as well none of those genres had any influence on stretchers that is just it could be argued sure but you would be wrong I mean king tut ( 1341 BC – 1323 BC)had stretchers I don't think black sabbath stumbled upon it that is for damn sure all those genres helped discover were drugs and sexual diseases
I can assure you today's modern use for this in no way religious or traditional , It may be slowly carving it's way into a part of North American culture but I mean you know it's nothing more then vanity . No man in there right mind goes out and says ... damn these 1 inch and a half stretchers really make me look like a man I mean hell I can fit my fist through it chicks must dig that right? (sadly yes because they are just as brainwashed as the fool who allows his ears to get cut up so it can look like a cats asshole) but to not drag this on too long and get to the point . Do I have a problem with gay's yah I think that is a stunt in evolution but my primary concern is with people making incredibly stupid choices even if it is none of my business because the less monkey eared, inked up , absent minded fucks I have to deal with the better for me the better for the rest of the earth , because the person worrying about what size there ears are stretched too are more then likely not making informed decision and they are more then likely not doing anything to further the progress of the world I live in that would be the main problem I have I guess
Metal just happens to harbour a lot of these individuals, also New wave is the 80's not 60's :P
