Jersey seashells 

Plastic tampon applicators. Particularly the old pink Playtex brand. These non-biodegradeable goodies were particularly prolific along the Mid-Atlantic coast in the '80s and '90s. Fortunately, you don't see them as much today.
We don't go to that beach anymore, there are too many Jersey seashells in the sand.

She sells seashells by the seashore

She sells seashells by the seashore

She sells seashells on a seashore 

This is the lyrics of the Popular meme "Luigi sells sea shells." Orginated from "Renn - Money game part 2."
She sells seashells on a seashore
But the value of these shells will fall
Due to the laws of supply and demand
No one wants to buy shells 'cause there's loads on the sand
Step one: you must create a sense of scarcity
Shells will sell much better if the people think they're rare, you see
Bare with me, take as many shells as you can find and hide 'em on an island
Stockpile 'em high until they’re rarer than a diamond
Step two: you gotta make the people think that they want 'em Really want 'em, really fuckin' want 'em, hit 'em like Bronson
Influencers, product placement, featured prime time entertainment
If you haven't got a shell, then you're just a fucking waste, man
Three: it's monopoly, invest inside some property
Start a corporation, make a logo, do it properly
"Shells must sell", that will be your new philosophy
Swallow all your morals, they're a poor man's quality
Four: expand, expand, expand
Clear forest, make land, fresh blood on hands
Five: why just shells? Why limit yourself?
She sells seashells, sell oil as well
Six: guns, sell stocks, sell diamonds, sell rocks
Sell water to a fish, sell the time to a clock
Seven: press on the gas, take your foot off the brakes
Then run to be the president of the United States
Eight: big smile mate, big wave, that's great
Now the truth is overrated, tell lies out the gate
Nine: Polarise the people, controversy is the game
It don't matter if they hate you if they all say your name

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.
