Masturine 

A derivative of the Gaelic word "rochardcochpee" it directly translates into urine of the mast. It is when you urinate with a rock hard erection, often while simultaneously ejaculating. It is something that only a select few can master, and when done inside of a women is considered a huge compliment. Most will deny wanting such an act out of fear of embarrassing their partner due to the level of difficulty involved, but every single female desires this.

"Hey man did you hook up with that girl last night?"
"Not only did I hook up with her, I filled her with masturine"

Mastering Chemistry 

A website created to make the lives of American college students a nightmare through the use of nazi-like grading on significant figures and rounding throughout 15+ pages of hell. Commonly referred to as a bitch for changing 1 number in each person's given values to piss people off.

"Hey have you done the Mastering Chemistry for this week yet?"

"No but I heard it's a real killer."

"Yeah I tried the hints and couldn't even work through those!"

Mastering Engineering 

An online homework program designed to rob college students of their hard-earned money and serve as a crutch for professors too lazy to write their own homework assignments or to teach. Its purpose, beyond making millions for the publishing company, is apparently to reduce the number of engineering graduates in the United States by utterly demoralizing and destroying their confidence in an effort to force them to drop the program and/or kill themselves.

I used up all but one attempt on this stupid Mastering Engineering problem, before I realized it had switched everything to kiloOhms instead of Ohms! And then I still got it wrong! FML!
