Cross-Thumbing 

Cross-Thumbing is a technique developed by Dr. Mark Ringwald PhD. and Dr. Nick Pollack PhD. at their video gaming ergonomic laboratories at Brandeis University. The technique is mostly applied when playing the Nazi Zombie segment of "Call of Duty: World at War". The technique consists of controlling the right thumb stick of an XBox 360 controller with one's left thumb while the right thumb is occupied with pressing one of the four buttons above the right thumb stick. The crossing over of the left thumb across the center of the controller, and in said gaming application is most useful while rebuilding barriers in the zombie level's windows to slow down the flow of zombies in the house. The technique allows the player to repair said barrier as well as aim and dispatch targets within the level.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
