ELI5: What exactly is happening when a game is "loading"

I'm sitting here waiting for someone's toaster to complete loading the game, (league of legends) and it got me to wondering what exactly is the program doing while it loads. What does it mean to "load" the game.

The program is copying all the data it will need from your hard drive (slow but permanent storage) to your RAM (non-permanent storage, but very fast).

The program might be doing more than this, but that will greatly depend on what the program is.
