grim grins 

Ironic and somber-faced jest used to temporarily make light of a serious matter, situation, or topic, in order to help everyone involved to maintain his sanity and composure about it.

Concerned citizen #1: Well, if the nuke-plant does blow its top and blankets everything for 1000 square miles with glowing radioactive fallout, at least it'll save on batteries --- we won't need flashlights to see at night.
Concerned citizen #2: Yup, that thought's a case of grim grins, all right!

Grim grims juice 

A purple milkshake distinguishable from the Grimace Shake. It is made of blood and tears from Jacob G. It is described as tasting like the favorite food of whoever is drinking it. When consumed, the third leg of the consumer grows by seven inches. The consumer will also begin to act like Jacob G.

Guy 1: “Have you had the grim grims juice?”
Guy 2: “Yeah it’s the best thing ever”
