Common Sense

Basic logic that the majority of this planet lacks. (Ex, most booksmart people)

Wow, this is the smartest kid in my class. He can't even sharpen a pencil. He really lacks common sense. How will he even survive in the real world.

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.

teen common sense

This is what adults use when they think they are supposedly smart.

I'm giving a word an extra prefix because why the fuck not? It'll make me sound smarter.

"I hate teens who use teen common sense, unlike normal common sense."
