This natural phenomenon has been around since the dwarven days of old. When two men desired anal they would conjoin there anus's and one partner begins by defecating. Once the fecel matter has penetrated the parallel anus the sphincter reacts and takes in the feces and mothers it as if it were its own. Once the anus has acquired its new bounty it relieves its self back from whence it came. Once statrted, the petpetual anal motion can not be stopped or disturbed by any means or this very act would be defying god himself and all life would end.

The mean is the mean

-Jeffrey M. Rossi
A 10 on an exam with a mean of a 10 is better than a 99 on an exam with a mean of 100.

"I got a 99...oh I got a 10. But by Rossi's Postulate we did the same."

To refer to a girl who is smart and has a big booty, hence the "ssa" (backwards of this spells "ass") part of the ssa postulate.

A girl who is an SSA postulate is most likely worth hanging around with because she can help you in ways more than one.
Half-Nerd 1: Remember that girl last night from our study hangout?
Nerd 2: Ah, yeah, what about her?
Half-Nerd 1: She is such an SSA postulate!

Nerd 2: {tries to recall the definition of "SSA postulate" from urban dictionary} Well, I haven't looked her over yet.
Half-Nerd 1: You gotta, she is *so* worth it!
Nerd 2: Is it more how she looks or her smarts?
