This is a blue screen of death belt buckle. It costs $17 and is currently on back order until November because everybody wants one for Halloween so they can dress up as people with novelty belt buckles. Pfft, like that'll win the costume contest.
The Blue Screen of Death (also known as a stop error, BSoD, bluescreen, or Blue Screen of Doom) is a colloquialism used for the error screen displayed by some operating systems, most notably Microsoft Windows, after encountering a critical system error which can cause the system to shut down to prevent damage.
Let's just hope the wearer of this sexy geek belt has a bit more luck!
How can you tell if a geek belt is sexy or not? Because looking at this one I wouldn't have known. But now that I do I'm gonna wear like four around my head like karate headbands. Sweep the leg, GW!
Thanks to naas, who doesn't need a belt because boxers have elastic bands.
