Top definition
A math equation that decides if somebody (normally a female) can be considered slutty.

The equation is shown below:
(# of past partners) / (age - 10) = X

X<1 Good girl, the kind you take home to mom.
X=1 Average, there is nothing wrong with being normal.
X>1 SLUT, fun to play with but generally crazy.
Guy 1: Rachel looks cute, but with my Slut Math skills I have determined she is a slut.
Guy 2: How did you do that?
Guy 1: Well she is 16 years old, and has slept with 18 guys. It is simple math, 18/6=3.

Guy 2: Damn dude, you're right, she is a super slut!

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).
