One of the most irritating and obnoxious things people say is: "no offense" .
If you want to make some sort of statement or voice an opinion... JUST SAY IT! Don't apologize for having an opinion. Saying "no offense" can make your statement come off more offensive than you meant for it to be. Seriously though, this phrase can make even the nicest people come off as a total snob.
Now, I'm not condoning going around saying stupid things and not caring about hurting people's feelings but if you're truly afraid of offending somebody... then think before you open your big mouth! And choose your words carefully.
And if you just like being plain ole' mean and think by saying "no offense" makes it all better... too late. You'll look like a jerk with or without saying it.
For those who thrive off of using the phrase, here's some pointers. (thanks to http://www.encyclopediadramatica.com)
How to use "No offense, but..." in your daily speechings
- Before you make a statement, don't think. Ideally, you should achieve a Zen-like blankness, which is conducive to fucktardery. If you have to think, focus on cookies. Or bears, or bears made of cookies. Anything but what you're about to say.
- Make sure you have everyone's attention. You are the most important and educated person in the room. This is mission-critical.
- For maximum impact, just open your mouth and let a bunch of random shit fall out. This is called verbal diarrhea.
