Most Notably Recognized from Southpark Episode "Make Love, not Warcraft", where Stan calls his dad an Ardtard for not knowing about World of Warcraft, and MMORPGs.

Usually referring to a person of lower wits, closely related to a retard, an uninformed idiot.
"I am socializing with people from all over the world, ardtard, its called MMORPG..."
