"No offense intended"

If you end a comment with "No offense intended" you probably should not have said the comment in the first place. "No offense intended" does not excuse your words or actions, it doesn't make it "ok" it just makes you sound like even more of an arse. It's like saying "I know this is going to piss you off to no end and hurt your feelings but I just don't care so here it goes". Blah grow up people...no offense.
