matsushima marina

Super busty Japanese porn star. Matsushima Marina loves to be the aggressor in her films and has a much better disposition than 90% of the other JAV (Japanese Adult Video) starlets. Meaning she actually enjoys having sex and doesn't sound like she's being tortured.

Look at the rack on Matsushima Marina! I bet she gives a titfuck that would make a dead man cum!

US Marines

The amphibious warfare branch of the United States military, formed on Nov. 10th, 1775. Tun Tavern in Pennsylvania is considered the birthplace of this branch. The US Marines are in particular used as an invasion force, rather than an army of occupation, and is the only US military branch that is deployed during peacetime.

The US Marines were the first force to deploy into both Iraq and Afghanistan.

Marinated Turd

When you take a dump, then piss on top and leave it to soak overnight. If the turd is particularly powerful, and the toilet seat is left down, the resulting stench is fucking brutal upon discovery.

This morning I was greeted by a marinated turd when I went into my bathroom.

That bitch pissed me off, so I left a turd marinating in her toilet.

margin magic

To doctor the margins of a word document so as to meet the minimum page requirements for a class assignment without actually coming up with additional material.

Jon: "How's that paper coming, Bill?"

Bill: "It's done, thanks to a little margin magic. I only had to increase the side margins by .1 inches!"

Jon: "That's dope."

diminishing marginal returns

phenomenon in which greater input of effort, money, etc. yields smaller results. Crucial part of the idea is that if you're using x to get y results (where y is the thing you want). then additional input a will yield additional results b, but not in the same proportion as before.

On average, before, you put in x to get y, so your yield was y/x. But if you increase x by amount a, then your results will be y + b, where

(y + b)/(x + a) < y/x

and this will only get worse.

Diminishing marginal returns (DMR) is used to explain why the supply curve in economics slopes upward, i.e., increasing the quantity supplied requires an increased price of most things.

Sometimes DMR is more than offset by "economies of scale," which allows more of a thing to be supplied more cheaply than a small amount.

At first his flowers and treats swept her off her feet, but then he had to do more and more lavish things to please her. It was a classic case of diminishing marginal returns.
