10 Seinfeldisms That Became Part Of Our Everyday Life

10. Re-Gifter

Elaine gave Dr Whatley a label maker as a Christmas present, only to see it crop up in Jerry’s apartment later on. This prompts them to label Whatley a "re-gifter."

This episode spawned the wide use of re-gifting and de-gifting (after Jerry tries to de-gift, i.e. take back, the Super Bowl tickets he had given to Whatley). In fact, the Oxford dictionary cites this episode's script as the first recorded mention of the terms. Apart from that, it seemed to change people's general attitude towards giving and receiving used presents.

Interestingly, the script was originally written by Alec Berg and Jeff Schaffer, and both Jerry Seinfeld and Larry David liked it so much that they didn't want to make any changes of their own.
