Grins 

A play on words of the Pittsburgh expression "Yins" and the bud expression "Greens." Mostly exists to make fun of pitssburghians.

Grins and Giggles 

For the hell of it, what harm would it do, we might even benefit from it. I believe originated from military-speak.

"For grins and giggles, let's click on this icon and see where it take us."

"Hey, we've got some extra time...why don't you turn down that road for grins and giggles and see where it leaves"

"Why are you wearing that awful looking hat?"
"For grins and giggles."

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!
