Common Sense 

Widespread, socially acceptable lies. It is used mainly by older people to insult people they disagree with.

"Too many illegal immigrants? Deport them all. Too many gang problems? Go buy a gun and shoot at them. Bad economy? Just cut the food stamp and all those welfare bulls***. That's just common sense."

"Climate changes all the time. I don't know why common sense is no longer common anymore."

Common decency

Something your boring roommate says to you when he doesn’t want to hear your bangers at 11:00 am on the day of the only darty that he will ever have the pleasure to enjoy.

“There’s a thing called common decency, and I don’t want to hear your music at 11:00 in the morning because I’m lame. Hee hee.”

What one without common sense believes as the meaning... "people who have spare change such as dimes and nickels, common cents"

Common sense isn't so common

(phrase / life observation / savage truth)

A brutally honest way to say that just because something seems obvious, most people will still find a way to mess it up. Perfect for moments when humanity disappoints you, usually in public or online.

Used when:

Someone does something completely avoidable or facepalm-worthy.

You realize society collectively skipped the “how to adult” manual.

You want to sound smart while judging idiots.

Meaning: Humans often act in ways that defy logic, and that’s on them.

Synonyms: “Apparently, this is optional,” “Logic is rare,” “Humanity, why?”

Examples of contexts in which common sense isn't so common:

Coworker: “I put metal in the microwave.”
You: “Common sense isn’t so common.”

Friend: “I just walked into traffic because I was texting.”
You: “Common sense isn’t so common.”

Internet comment section: literally anything ever.
