Neutron Bomb 

When you enter a public restroom in order to relieve a copious quantity of the contents of the bowels, and it just so happens that the smell can only be thought of as "Eau de Subway Homeless". The result makes people choose another restroom on another floor, another building or just hold it until they get home. Neutron Bombs are frequently detonated at roadside rest stops, county park latrines, mall food courts, other people's house parties, corporate environments where you didn't get the job, corporate environments where you haven't gotten a raise in three years, corporate environments in general but not on your floor, or at the bathroom display area at a home improvement store.
"The Kung Pao Chicken from Kar Won gave me some serious rumbles. Don't go up to 6th floor, I had to drop a neutron bomb there."

"Are you kidding? Right after lunch?"

"Yeah, the fallout is leaking into the hallway."

Olivia Neutron Bomb

A nickname for Australian pop singer and actress Olivia Newton John, who rose to fame with various songs around 1974 and 1975, one entitled "Have You Never Been Mellow?" During this time, nuclear armament science heralded a new invention known as the neutron bomb. It was able to disperse devastating concentrations of life-destroying neutron radiation while leaving buildings and structures intact. Men and boys who didn't appreciate the lilting voice of the singer, who later starred in the Hollywood films Xanadu, def. 1 and 5 and Grease were known to call her by this name. Although they may have fantasized shagging the well-scrubbed songbird, never would they admit to enjoying her enchanting dulcet tones. The name is considered belittling by a Xanadude, and subliminally resembles the title of the rock band known as Olivia Tremor Control.
Dennis turned off the radio in disgust and cued up some heavy metal albums. "Not Olivia Neutron Bomb again. Isn't she ever going to shut up?"

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.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
