Sorry man I’m adapting to the 37 Rule from now on.

I'm 37!

The age when half of the population is younger and the other half is older. Where one leverages responsibility and fun with better precision. Drinking is still fun but comes with severe hangovers. Partying in general is limited.

Hey, want to shotgun a beer? "Probably not a good idea. I'm 37, Bro!"

You made the right choice by skipping the shots. "I'm 37, Bro."

"Michael Jordan is the greatest of all time. I was there. I'm 37!

37

Used to describe someone who is being unnecessarily difficult, boring, negative or just generally killing the vibe. Saying "Don't be so 37" is a friendly way to tell someone to chill, stop complaining, or loosen up.

Comes from Norway, where "37" is used as a playful code for people who overcomplicate things or make situations less fun. The exact origin of the number is unclear, but it just feels like someone who would argue about the rules of UNO.

Don't be so 37!
