Human Subclutures are nested fractally!

I have been playing League of Legends lately and have noticed this.   It is a subculture, in a subculture and even particular chat rooms have a subculture.   It is quaint and endearing.  (Note: the language, abuse and conversation are not endearing at all.   They need a mother in the chat room to wash all of their mouths out with soap).

I see this at work too, especially the nesting.
