autoerotic hyperventilation

hyperventilating 

You breathe without thinking because your body does it for you automatically. But things can change your breathing pattern and make you feel short of breath, anxious, or ready to faint. When this happens, it’s called hyperventilation, or overbreathing.

That’s when you inhale much deeper and take much faster breaths than normal. This deep, quick breathing can change what’s in your blood. Normally, you breathe in oxygen and breathe out carbon dioxide. But when you hyperventilate, the carbon dioxide levels in your bloodstream drop too low. You’ll notice it right away because you’ll start to feel sick.
hyperventilating is not fun!

rectal hyperventilation

A condition where the rectum has a quite rational fear of being penetrated by a large member (again) and therefore has a reaction akin to a "panic attack"-causing the owner of said rectum to faint and therefore become incapable of participating in said sexual act-to the great relief of the rectum.
"Hey Baby-hows about some kinky butt sex"
"Sure Hun-lets go"
Anus...."Fuuuuuuckkkk....Noooooo.....Im still sore and slightly stretched from the last time..noooo..this causes physiological symptoms of "rectal hyperventilation" similiar to a panic attack where the "flight or flight"mechanism is hampered by the butts inability to send nerve messages to the legs to get the fuck away-instead it causes "Baby" to collapse in a faint in a public place making anal sex impossible or at least illegal!

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.
