highest common points

In a sport, especially basketball, where the winning team is determined by the highest common points amongst the players. Traditionally the team with the highest total points wins the game. However, with highest common points each and every player or position has to score a point to count towards the total score. The purpose being that every member makes sure that everyone gets a chance to score so that no single player hogs all the points.

Player A score 7 points, Player B scores 2 points, and Player C score 10 points. So the total highest common points for the team is 2 points. Player A and C should wait give more chances to Player B, and Player B should try more on his/her own to score more points for the team to win with the most highest common points.

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.
