Can anyone explain this phrase for me, please? "umbrage-taking characters from a Seinfeld episode"?
This is the context it was in:
On the other hand, some of us are easily triggered — and can’t resist our first impulse. We have to speak up. This is how ugly public scenes begin. These tiny annoyances should trigger bemusement over life’s rich tapestry instead of turning us into umbrage-taking characters from a Seinfeld episode.
