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.

Giesel's Law of Diminishing Returns 

The more porn you watch, the more hardcore the porn has to be for you to get an erection and to finish. For example, if you watch porn sporadically regular straight porn will do the trick. However, if you're a Giesel and masturbate 13+ times a day it will take some seriously hardcore bukkake or brazilian fart porn to get you off.

Palmer: Dude, last night Lesnick was locked in his room for like twelve hours straight masturbating. You know he had to be wanking to 2 girls 1 cup or some beastiality incest or something.

Pat Shea: How do you know that?

Palmer: Cuz of Giesel's Law of Diminishing returns, that's how

Diminishing Returns

When somebody farts multiple times in one instance, with each fart getting smaller and quieter. Can be anywhere between 3-6 farts. If someone farts more than 6 times in one instance, they need medical assistance, not the Urban Dictionary.

"PPFFFTTT PFFTT Pffftt pfffft pfft pft."
"Damn Daniel, those were some diminishing returns if I've ever heard one."
