Possibly the easiest phrase to use to embarrass somebody and make them feel stupid in front of others. Especially someone who's coming up with shitty comments while you're trying to have a laugh. Your disregard to this person's comments can cause great damage to their self esteem. It can be used to destroy an annoying little shit's confidence, so that he doesn't speak for the rest of the night (only if used with skill and passion.)

when somebody make a very bad joke and nobody laughs there is a pause and anybody can claim a NO! this is where anyone that thinks the joke was stupid and not funny can say no! The no has to be said in a jokey manor as your tlaking to your friends and they will mostly likely know it was a bad joke.

Most no jkokes are not prepared as jokes they are said in the moment and really should have not left the mouth.

so in conclusion a No joke is a joke that is not funny and its infact shameful.

The phase in any conversation, usually occurring every 20 minutes or so, where the conversation gets quiet and no one really knows what to say. This is the point in the conversation where everyone involved will be desperately fishing for topics and might take up talking about the weather.
