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.

The only time you would use this little phrase is when you are going to insult someone to the point of pissing them off. Just because you say it doesn't mean you can say whatever you wish afterwards, and if someone has a comeback to your insult you can't throw it in their face that you said, "With all due respect." You should use this phrase wisely, you might piss your girlfriend off with it! :-)

Kylie-"Don't even get us started on you!"

Kylie- "And just because you said, "with all due respect" it doesn't mean you can say whatever you want it simply means, CAUTION I'M GOING TO BE AN ASS WITH THIS COMMENT AND I WILL REGRET IT LATER!!"
