Word Origin:
Middle English (originally denoting a heretic): from Middle Dutch, from Old French bougre ‘heretic’, from medieval Latin Bulgarus ‘Bulgarian’, particularly one belonging to the Orthodox Church and therefore regarded as a heretic by the Roman Church. The sense ‘sodomite’ (16th cent.) arose from an association of heresy with forbidden sexual practices; its use as a general insult dates from the early 18th cent.
