A conversation that lasts significantly longer than any party intended, and which may result in an unexpected dead cell phone or need to re-hydrate due to its surprising length.
There was hardly a topic we didn't talk about during last night's marathonversation, after which I had to charge my cell phone and re-hydrate.
