Has anybody ever said, "Uh, but, seriously dude. No offense. No offense man. No offense."
I mean, Come On.
First of all, if you're going to say something offensive, then it's offensive. That's that. You're going to be offensive.
If you don't want to be offensive,
DON'T BE!
The reaction I have is
A. The person is so nervous about being offensive when he actually isn't being offensive, that he sounds like he simply has no clue (And honestly probably doesn't. He should just shut up. And he should know that already)
B. The person is being offensive, and the "no offense" thing is a reflexive defensive statement, which is pathetic and, ultimately futile. If you say something offensive to me on purpose like that, saying "no offense" will not take anything back, nor will it prevent me from taking offense anyway.
The topic is actually a fairly serious question:
Can anybody think of a convincing scenario where the phrase "No Offense" can be used effectively?
Or is it just a dumbass statement that ought to be abolished from the language on pain of a good punch in the gut?
