Average friends 

When two or more friends engage in average friendly banter/conversation, casually.

So there we were, just a few average friends sitting around chewing gum with some casual laughs and stock conversation topics.

Timothy: What were you up to last night, Michael?
Michael: Oh not much, just hung out with some average friends and exchanged standard, run-of-the-mill stories about generalizations.
