It’s actually very well explained. Some people ask me what are cookies but I don’t really know how to explain that. I just tell people that it is basically information from the website that is stored in your computer and you can’t eat them.
Google does the explanation much better here:
By the way, do you pronounce ‘privacy’ like it’s ‘pre’ or ‘pry’?
Django’s session id cookie used to be called ‘hotclub’ until people start deeming it too pornish.
Django: Now 10% less pornish
We’ve changed the default session cookie name. Instead of “hotclub”, it’s now “sessionid”. Intended as a reference to the Hot Club of France (one of Django Reinhardt’s bands), “hotclub” had been misinterpreted by some people as having some sort of porn-site meaning.
Oh, well. Wit and obscure references only go so far.

And you can see from the changelog:
Of course, if you much prefer ‘hotclub’, you can change it back with the SESSION_COOKIE_NAME setting.
Pretty amusing I say.
