Possum up

A phrase that can be used two different ways. You can use it to tell some to be laid back about something. Or it can be a way of saying hunker down and get it done.

Mom: You're not supposed to be playing video games on school nights.
son: come on mom just possum up.
Example 2.
guy 1: I have a lot of work to do tonight.
guy 2: I guess you'll just have to possum up and get it done.

Bone Cobbler

The most venomous type of snake in the universe. The potency in a single drop of the venom has the power to decimate Jupiter 5 times (or half of your mother). The only thing that can kill this creature is a wild boar on copious amounts of French cocaine, or an extremely buttery corndog.

Guy 1: I'm going to the swamp today to go hunting.
Guy 2: Watch out for Bone Cobblers.
