vial neptune 

A Vial Neptune, (or Vial of Neptune), or simply "Vial", is beautiful young woman capable of anything. She is intelligent, beautiful, dark, pretty, and mysterious. She believes in Lilith, she studies the dark arts, practices witchcraft and Tarot, and has the ability to captivate your soul. A woman like this in the past would have been referred to as a "Goth", but a Vial, short for Violet, is just that: a Vial of dark beautiful energy beyond superficiality, fashion, style, etc. It is a feminine resurgence, an emotional intelligence, a divine and powerful woman. The first Vial was Brittney Lazo Rodriguez, from San Deigo. A powerful witch, protected by the spirit world, and stunning in every sense of the word. If you find yourself a Vial, treat her like the Queen that she is.

"She's not a goth, she's a Vial. A Vial Neptune."
"What's a Vial.. Neptune?"
"If you need to ask, you don't deserve to know."

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.
