Ring culture

A belief that success in sports can only be measured by championships (members of championship teams are typically awarded rings, which is where the term comes from).

In a season where a team does not win a championship, those who believe in ring culture identify said season as a failure, regardless of how close to a championship said team was.

Fan 1: "I can't believe my team just lost the Super Bowl. I'm not wearing any of my Super Bowl gear ever again. This year was horrible!"
Fan 2: "Ring culture is ruining the experience as fans. Just be happy that your team made it to the biggest stage."
