Registered Pension Plan - RPP
  
O Canada! Where you can go curling with a moose, and then eat some poutine, washed down by a bag of beaver milk. Also, where you might run into a registered pension plan.
The definition for this one is pretty much right in the name. It's a pension plan recognized by the government. Both employees and their employer get tax breaks to contribute funds to the plan, which pays out benefits to the employees in retirement.
