Rataplan 

To plot or scheme in a decidedly rat-like manner, esp. when formulating an agenda for the acquisition of cheese and/or shiny objects.

Just look at those two nefarious-looking furry midgets in the corner there... they are clearly rataplanning something.

Rataplan 

The planning stage for an event that occurs after the pre-plan but before the actual preparation for the event.

"I don't want to shower and get ready yet, I have like three more hours to rataplan before I have to do any of that."

ratplanet 

Planet Earth, or any location, when implying its social decay or lack of morality.

I'm just waiting for some loser to blow up this miserable ratplanet.
