with all due respect
In military parlance it means 'no more respect than protocol requires me to show'. Opposite of the term: 'with respect'.
Said to a superior, a means of veiling contempt adequately enough to evade disciplinary action (depending on the words following it.) Applied frequently by top brass toward Congressmen during Senate Committee Hearings.
Said to a subordinate (rarely,) it sarcastically emphasizes how little respect the superior is required to SHOW, and how much less they're required to HAVE for the subordinate.
