The measure of an item's resale potential on the popular US-based auction website, eBay®.

Specifically, an item that has a high eBayability will be easily sold for a profit on the auction website.
A "long lightsaber" Luke Skywalker POTF action figure MOMC at a yard sale for $1.00 would have an extremely high eBayability.

Whereas at the same yard sale, a worn copy of "Madden NFL 06" for XBox for $15.00 would have an extremely low and quite possibly negative eBayability.

n.b. U.S. Dollars is not necessary to define an item's eBayability as Ebay operates in countries that use other currencies. It is however, necessary that an item be sellable on the website.

Derogatory term used in online gaming (see MMORPG, MMOG) to describe someone who has not earned the equipment or character they are using. Often high-level players will use eBay to sell premium equipment they have earned in-game, or sometimes sell an entire account, with all characters and equipment, exchanging real-world money for in-game items. This practice is generally discouraged by the companies that produce and host the games. Someone who has acquired their character or gear in this way is generally recognizable by inept game-play, which would not be expected of someone who has actually earned their position.
Player 1: I just met this guy, a level 195 Enforcer wearing a full suit of living dragonscale armor, and he didn't even know how to find the shops in Old Athen.

Player 2: Just another clueless eBayer!
