AMERICAN PHRASE, widely considered by some to be a cliché. Two uses of this phrase.

#1. No pun intended! Is a clarification you make after a remark you uttered that DID indeed contain a pun. You exclaim, No pun intended because you honestly did mean to construct the setence to contain a pun.

#2 The second meaning of, no pun intended can be tongue-in-cheek or more harshly put, untruthful. In this instance a person purposely inserted the pun. The motivations for doing so vary. Some reasons include: doing it to be humerous, attempting to be clever, wanting to engage in word play, or doing so to annoy people who hate puns. They fib by saying, No pun intended! because: they want to avoid embarrassment after no one laughed, escape retribution from those they annoyed on purpose or perhaps they feel foolish for making the pun at all.

Ive read every definition here and they all get this terms meaning slightly wrong. Firstly a pun is a play on words, intended to be semi-absurd and comical by describing a thing or situation using words that could also describe the situation with another meaning. For instance suppose there was a skinny farmer picking berries, but he doesnt find that many, another person might observe looks like slim pickins.
Puns often are the worst kind of joke because they do not require much cleverness.
When someone says no pun intended, however, it is when they say something that could be taken to have two meanings; an obvious one, and a slightly off interpretation; and they want you to know they are not making an intentional play on words and want you to take what they said to be the obvious meaning:
