For the common good 

A term used by communists and socialists to push their agenda, such as saying that the lockdown is "for the common good."

"I know they say the lockdown is for the common good, but how could it be for the common good if it kills the economy?

It is also not 'to save grandma,' because otherwise they would let her see visitors in the nursing home. 'For the common good' seems communist to me."

Dumbest Common Denominator 

The most logically-challenged portion of the general population for which the most obvious warnings, posts, signs and instructions must be written or designed to avoid catastrophe.

On the lid of the coffee cup: Contents may be hot.
On a package of kitchen knives: Caution! Items are sharp.
On a trash bag: Do not place over head.
At a railroad crossing: No parking.
On a clothes dryer: Do not place children or animals inside.

"This is the dumbest sign I've ever seen. Do they think I'm a complete moron?"

"Dude. Gotta plan for the Dumbest Common Denominator."
