brainspike 

Verb: the act of watching a particular series (usually but not always anime) of episodes or movies in a row.
(especially the ENTIRE series at once)
Noun: the series to be watched.

Originated from Eau Claire, Wisconsin. It was created as a more polite/useable form of mindfuck (which means the same thing) by the local university's anime organization. Apparently watching many hours of anime episodes straight does something to you in the head.

Noun: The brainspike starts at 6 and ends four days later.

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.
