friction pile 

A group of people rubbing vigorously against each other for warmth.

We were cold, so we formed a not gay friction pile to stay warm.

exotic fraction 

A fraction that you might have to deal with when doing a college-level homework problem. It doesn't necessarily have to contain X or any other variable, but it does have to have to be a numerator-denominator combination that you would not normally see in everyday life. The reason the number is written as a fraction is because writing it as a decimal would require imprecise rounding off and/or because it must be added, subtracted, or multiplied with a similar fraction.

Okay, so we just got through establishing that:

(61/99)X = (8/49) + (56/22)Y + (45/38) - (1/36)Y{(14/45) - (31/29)Y} - (2/7)X + (1/18)XX

can be simplified as:
(625/693)X = (2509/1862) + (1/18)XX + (22603/8910)Y + (31/1044)YY

which can be further simplified as:
X = (1738737/1163750) + (77/1250)XX + (1740431/618750)Y + (2387/72500)YY

*loud sigh* There!! Now that we're done with that headache, I don't want to see another exotic fraction for the rest of the day!

fat friction

Fat friction is generated from the rubbing together of thunder thighs when obese people walk. It has been estimated that a chubber wearing corduroy pants can generate 800 BTUs of heat-enough to make a grilled cheese sandwich.

My girlfriend melted the crotch out of her nylon wind suit with fat friction.

Derived from a play on words for ass "whole". When using insert the appropriate fraction in the insult

<A> don't be an ass half.
<B>What did you call me?
<A>An ass half, because you are so pathetic it would take two of you to make an ass whole.

Slang for "nose picking", funny because it sounds like "science fiction".
