Just skimmed this thread for the first time. Regarding "bugger": Did I miss anyone noting that "buggery" is an old term for anal sex? I've never encountered it outside old literature, or heard anyone refer to it literally, except once.
I spent about a year in Canada 30 years ago. I happened to refer to someone's cute little kid as "a cute little bugger". An old church deacon took me aside afterward, and told me that what I said could be taken as a gross insult; I was calling the kid a "Sodomite". I've probably called kids that at least a few time since anyway, and I've never seen anyone blink or faint.
