Meaning of the term 'plotless' I need an elaborate answer to this question. After one of the answers I got from another question where a particular film jargon ("plotless story") was used, I read a wiki page and found that plot (narrative) means the chain of events which are linked to each other. In every show which is made for entertainment, there must be a link between events otherwise it would make no sense to watch it. Imagine a hypothetical "plotless show" where two characters completed unrelated to each other, die because of completely unrelated reasons, it'd rather be called a set of random events rather than a show. 

When people say "this anime has no plot", what do they actually mean? Are they talking about two episodes not connected to each other?
@torisuda has it correct:


  It means a story that lacks an overarching narrative


For an example of a plotless show, see Lucky Star.

The characters are the same in each scene, but every scene is distinct from each other. In one scene they might be talking about how to eat a chocolate cornet, another they might be talking about video games.

There are jokes that are referred to again - for example how Kagami is a tsundere. But this isn't a narrative or simply put - a story. 

Your definition of narrative is correct:


  the chain of events which are linked to each other


but, it fails to contextualize the links. the links are items that further the plot's progression - for example: a hero beats a villain who was blocking the path, the girls perform in a concert that raises their fame, etc.

Links like reusing jokes, same characters - or generally things of no overall consequence do not contribute to the story/plot.

If we have no links like we described, the show can be called plotless.

Feel free to comment if you want me to expand on something.
