obsidiot 

Those who are amongst the ranks of Fallout fans who believe New Vegas is the be all-end all of the series, and will venomously, and maniacally defend their stance with the ferocity of Chricj Crocker defending Britney Spears while screaming into a webcam. These neckbeard adorned cock goblins are also known for screaming "drones " before launching into a badly spelled rant that you have to struggle up understand.

Matt: Holy shit, Tony's such an obsidiot.
Kevin: That emo kid needs to wash his hair.
