A joke, usually between no more then 10 people, and usually sounds like complete nonsence if you are not part of it. Usually, It is something that happened or what someone said that was really funny at the time.

If someone who was not there when whatever happened, and are told the story of what did, it doesn't count as an inside joke with that person.
