A member of the "The Married And Always Nagged"(or MAAN) clan in the PS3 game--Warhawk (and more recently COD4). The only requirement for entry is being married (edit--The Warhawk section of MAAN clan is now closed off to new entrants). These gamers are especially known for their good natured ribbing of each other during matches. They also seem to travel in packs, as you rarely see only one in a game. They have a great reputation in the PS3 community.
Dude, that MAAN clanner just took out 5 guys with a TOW. F-ing JSin!!
