emotional math 

when you use numbers to describe the feeling of something rather than rely on logic/actual math

"- my education cost me like a 1/4 of a million dollars"
"- wait. you paid $60K a year?"
"- no, it wasn't actually 1/4 of a million. it just FELT like it. i was using emotional math."

liver math

Liver math is the calculation(s) you make throughout the night to help determine if you are sober enough to drive home.

Alcohol is processed by the body at a determined rate (generally one beer/shot/wine glass an hour), and you can save yourself a night in the drunk tank and some legal fees by adhering to liver math.

Liver math or cab fare. Either is a wise choice. Disregard at your own peril.

Friend #1: "My ex just showed up here with her new bf. I'm leaving as soon as the liver math allows it."

Friend #2: "No way! You're my ride! Let's get fucked up and take a cab when the bar closes. I'll drive you to your car tomorrow."

Friend #1: "Good call. Screw that bitch, anyway."

Slut Math 

Slut Math
A math equation that determines the sluttiness factor of a female

log((age-10)^69)/18

take the age, subtract 10, take it to the 69th power, take the log base ten of that, then divide by 20 to get the acceptable number of sex partners from that age.

take the # of partners of the accused slut, divide by the equation above.
if above 1, then she is a slut
else, she is probably not, but may act like one.

-Dick- Hey I think Brittany's a slut
-Brian- Have you done the slut math on her yet?
-Dick- What's the formula?
-Brian- You take her age, subtract 10, take that number to the 69th power, you take the log base ten of that number, then you divide by 18.
-Dick- Ain't nobody got no time for that.
-Brian- But i do got time for taking my log and and 69ing with power(sex joke).

netflix math 

When you check the year of production against how many seasons are on Netflix for a particular show you are loving, in hopes the series may still be ongoing.

I did the Netflix math, and realized (insert favorite show) was over after the season I'm binge watching now.
