A game in which if someone says something stupid, another person yells "brains" and slaps the person who said the stupid thing on the back of the hand

Jim: Wasn't Bob Ross a scientist
David: Give me the brains *slaps Jim on the hand*

Smeg for Brains 

From the sci-fi comedy Red Dwarf.
Someone very stupid. A form of shit for brains. An insult.

"Hey, smeg for brains- get us another beer."

Acela Corridor Galaxy Brains

Acela Corridor Galaxy Brains is a phrase coined by the renowned economist and scholar in Sino-US-Europe study Christopher Balding to refer to people from Boston to the DC along the east coast who have never left their towns such as Cambridge, the borough of Brooklyn, or Georgetown but think they know enough to run the world such as journos or tankies. Acela is the "high speed" train line with a top speed around 90 mph for brief stretches.

China, with Acela Corridor Galaxy Brains' assistance, is pushing this nonsensical line that "let's repair the relationship but not talk about anything of importance."

grain bains 

Short, fat string beans which have been boiled for far too long. Served ubiquitously in the south.

Dude: "Somebody boiled the shit out of these green beans!"

Scary obese lady chef: "Don't you like grain bains?"
