Ebay is a large corporation with a lot of enemies around the world, resulting from its treatment of the customer (both buyers and sellers), near total lack of customer service, naked corporate greed, and corporate secrecy. The term "evilbay" has, not surprisingly, come into common usage when referring to the firm. It's commonly heard at flea markets and estate sales, and has become part of our modern culture. It clearly deserves to be officially added to urbandictionary.

A buzz word being used to refer to creators and influencers forming or encouraging unhealthy relationships with their fans. Usually used in the context of young audiences feeling they have a relationship with the influencer due to the huge amount of the influencer’s content they consume.

These relationships are exacerbated by the influencers confirming they have more than a creator-to-viewer relationship.

The word is circulating due to various YouTube essays about the phenomenon using the word, and therefore people who enjoy complaining about influencers repeating what they heard in the video in any comments section they can find.
