A person who regularly buys or sells items on eBay, the online auction and marketplace platform.
A modern compound formed from eBay (the company name) and the agent suffix -er. eBay itself combines 'e' for electronic and 'bay' suggesting a marketplace or harbor for commerce.
eBayer exemplifies how the internet age creates instant neologisms - within years of eBay's launch, users needed a term to describe their new identity as online traders. The word captures how digital platforms don't just facilitate transactions but create entirely new social roles and communities.
