What does a “fast/slow metabolism” really mean?

I mean, I get that having a fast metabolism means that you get fat harder and vice versa, but what does it exactly mean? And what are the upsides and downsides of each?

I have a personal theory about how the “fast/slow metabolism” misconception could partly be a function of how efficient people’s digestive systems are. For example, my brother has bathroom issues and can eat and eat and eat with no weight gain. He is therefore not absorbing his food efficiently. This could be an extreme case but you can imagine there being a spectrum of how effective people are at digesting their foods.
