ANAL-CRANIAL INVERSION SYNDROME  

A chronic condition by which the physical connections between the buttocks and head are reversed, causing fecal material to spew from the mouth. Conventional treatments include wiring the jaws shut or the prompt use of a gag ball.

ACIS is more harmful to those coming in contact with the ACIS person than the ACIS person him/herself. Even casual contact results in looks of disbelief, screaming and the uncontrolable urge to place one's hands over one's ears and yell "Make it stop". Family and friends living with an ACIS patient are advised to wear ear plugs, or in more extreme cases, to drive shiskabob spears through their ears.

Not to be confused with having Head-Up-Assitisis or Asshatoses.

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.
