Twinventory 

The act or action of constantly taking inventory or checking to make sure your twins (balls) are still there.

Dood, check that guy over there always grabbing his balls every five minutes. Oh don't worry he's just taking Twinventory!

WINventory 

Invented by TOY_ROBOT on the Ratchet & Clank forums, this is the place to put wins (Epic stuff).
Its opposite is the FAILbox.

Chuck Norris goes into the WINventory, while Rick Astley goes into the FAILbox.
