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.
