Definitions for "Overrated"
Overrated is a Horde World of Warcraft guild, based on the US Black Dragonflight Realm.

Before being banned, Overrated was the #1 Horde guild in the US, having completed all the pre-expansion WOW instance content before any other guilds in their faction and geographic locale.
When a player or team underachieves expectations caused by previous better play or constantly yapping his trap. Prime example: Warren Sapp.
