How to get free legitimate RP for practically nothing.

[duseg]

It is a legitimate method to gain RP for very little hassle, and is really pretty simple to do. Don't forget to rep if this helped you.
EDIT: Forgot to mention it is probably best to do it during your queue/champ select/loading screen time.
