gatehead 

A devoted fan of sci fi series 'Stargate SG-1' and/or 'Stargate Atlantis' and/or 'Stargate Universe'.

Biggest gateheads have joined online fandom, watch episodes on daily basis, and have SG marathon at least once a year. Long hiatus during new season can make 'em a little crazy.

Person #1: *keeps blabbering about Stargate and refuses to stop*
Person #2: Dude, you're a total gatehead.
Person #1: Why thank you.
