Efflowance 

Definition: The quality or state of displaying graceful, flowing, and effeminate movements or mannerisms, especially in speech, gait, or gesture. Often associated with artistic expression, such as in dance, music, or visual arts, but can be applied to everyday behavior.

Adjective Form - Efflowant:
Definition: Characterized by or possessing the qualities of efflowance; gracefully flowing and effeminate.

Etymology: A fusion of “eff-” (as in effect, signifying external manifestation) and “flow” (as in flowing movement), combined with the suffix “-ance” to denote a state or quality. The adjective “Efflowant” carries the same root meanings.

Note: Unlike historical terms that might carry negative connotations regarding effeminate characteristics, “Efflowance” and its adjective “Efflowant” are neutral and descriptive terms, celebrating the grace and fluidity of the movements they describe.
Efflowance - “Did you see that performer’s efflowance on stage? The way they moved was hypnotizing.”

Efflowant - “Her dance was so efflowant, every movement seemed to glide effortlessly.”

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.

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.
