Noun: (alternatively Gilga)

Gilgamesh was the name of a World of Warcraft avatar played by a wife who was using the VoIP service Ventrilo to cyber with the male players of other avatars in her husbands guild. When the husband posted this information to the WoW Onyxia server forums, the entire ordeal engulfed the WoW community over the weekend of 8/10/2007 before ultimately being quelled by forum moderators. There is some reason to believe the entire story was faked, however, the name Gilgamesh has become synonymous with cheating, loose women in the WoW community.
