Bugger. The word derives from Bulgarian gentilic . The origin of the term dates back to the ninth century, when Orthodox Catholics wanted to evangelize Bulgarian territory, where there was a very strong animist stream. To combat this they spread the idea that in the area of Bulgaria was a sect that practiced sodomy. Derogatory intention.
