I think this is southern term, but I haven't heard it spoken in years by anyone but me. It keeps The Lord out of the situation, yet the "hot" of it lets there be no doubt that were talking about hell. It sounds close enough to God damn to serve as a euphemism too.

South Park brought bastard back in focus, but the Dirty Bastard, which no doubt followed the words "Why you..." in old movies has yet to return in full force. Technically there many bastards about theses days, so what's the big deal?
