A phrase that gives the user the right and privilege to say whatever they want about the person they're talking to or anyone the two parties know, providing they say this before they begin their offensive rant. Can be substituted with, "I'm sorry, but..."
Commonly used by people who doesn't know how to spell "no offence", even though it makes absolutely zero sense. Like, how could you think that's the right way to say that, who's Noah and what is the matter with his fence?
Person 1: Noah fence, but that shirt is absolutely hideous
Person 2: what?
