Motherless Fuck 

An ingenious spin on the ever so versatile term "fuck." Derived from the bowels of a US Navy ship, the term literally means, well, exactly what is says: "motherless fuck." Motherless, meaning without a womb, and fuck... well, there're thousands of possibilities. A comparable term, Mother Fucker, can be used alternately when "motherless fuck" does not fit the context in a desirable fashion (though, I don't foresee many situations in which "motherless fuck" would not work...)
Antonym: Son of a Bitch

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
