Seinfeldian 

adj - to describe a chain of dates. To keep motivated to do an activity every day, Jerry Seinfeld used a large calendar and a big red marker. Everyday that had success got a big, red "X". The secret? “Don’t break the chain.” “Don’t break the chain.”

Max is still going to the gym everyday since he started using that Seinfeldian chain.

Seinfeldianism

The belief system, worldview, or lifestyle rooted in the obsessive analysis of everyday trivialities, awkward encounters, and the unwritten social rules of life—just like in the TV show Seinfeld.

Those who practice Seinfeldianism often:
• Get irrationally upset about double-dipping.
• Question close talkers, re-gifters, and low-talkers.
• Believe “nothing” is everything.

The practice of Seinfeldianism is worldwide and spot on in most cases. Seinfeldianism will live on for ages, not that there is anything wrong with it!
