What really is a third place...

I have heard all these definitions of a third place, what it should consist of, what it should provide and what not. However, I think a third place could be me going to a friends house and hanging out and sleeping over. Its a home away from home, its mingling with my friends, and if we want we can even talk about intellectual things like strategies on how to win Risk! Heck i can even walk around in my boxers if I so wished, to me that sounds like a home away from home.
