The regift joke comes from Seinfeld, the 1990s sitcom that turned regifter into a household word for someone who passes an unwanted present on to someone else. The bit became one of the show's most quoted etiquette debates, and short audio rips of it now circulate as reaction sounds. Creators reach for it whenever a gift looks suspiciously familiar, from holiday vlogs to thrift-flip videos, because the reference instantly tells the audience the present was never really bought for them.
