Gaming:

In some MMORPGs, the term RR may be referred to as "reset" or "reborn". As soon as you reach the level cap, you can restart with the same character from a lower level, retaining some benefits.

This mostly applies to some private servers for certain MMORPGs, but there is at least one official game that does it - Mabinogi.

"Roid Rage"

Sometimes called the double Rs
Person 1: I have some serious RR right now.
Person 2: Maybe you should talk to someone about that

It's pretty self-explanatory.
