Lying-ass Motherfucker Coefficient 

When dealing with a lying-ass motherfucker, the Lying-ass Motherfucker Coefficient (LAMC)is the multiplier (generally around .39) added to any numbers (such as income, number of recent sexual relations, cost of automobile, amount of alcohol consumed, length of prison sentence, etc) quoted by said lying-ass motherfucker, with the intent of approximating a truer estimate of the referenced events.

The actual value of the LAMC fluctuates depending on the relative purity of the lying-ass motherfucker in question and must be adjusted accordingly. A LAMC of .8 or .9 is only appropriate for a "part-time" or a "fly-by-night" lying-ass motherfucker, while a true, pathological lying-ass motherfucker often necessitates a .1 or even a .05!

Use a known quantity to assign a LAMC value to the lying-ass motherfuckers in your life. If, for instance, a lying ass motherfucker at your work claims he made a cool $120 in tips over the course of his shift when you spotted him pocketing a paltry $45, you can safely place his LAMC at .375, give or take a few hundredths.

Once a LAMC is established, it tends to remain fairly constant, varying only in cases of extreme mental excitement, anguish, or upheaval. Lying-ass motherfuckers who are manic drunks, for example, often require a lower LAMC value when they are on the sauce. Tears in the beer, however, can indicate that a higher value should be used ("in vino veritas" rings true, for depressive drunk lying-ass motherfuckers at least).

A final note: the LAMC only applies to numbers which the lying-ass motherfucker has motive to inflate (like the number of people it took to beat the shit out of him last night downtown). For instances where a lower number would seem "cooler" (such as the number of statuatory rape charges on his permanent record) a Reverse Lying-ass Motherfucker Coefficient (RLAMC) must be employed. The RLAMC will be covered in a later article.
Andrew: Man, Jacob was wasted when I came in last night! He said he drank a whole twelve pack when he was out with Tina!

Joe: Man, fuck that noise. You know that Jacob's Lying-ass Motherfucker Coefficient is a good .25 easy. He drank three beers, cried for a while, got Tina's voicemail, got ten other girls' voicemails, watched TV, and then passed out on the couch, which is where you found him when you came in.

Andrew: You're right, man. Dude's a lying-ass motherfucker. I don't know what I was thinking.

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.
