mastowering 

Masturbating in the shower, quickly and/or efficiently. To make the distinction from 'masturbathe' (which can be a more drawn-out process).

Nothing like a good mastowering session to start the day right.

Mastering Physics

Literally cancer. Homework website used by colleges to make students google every question on chegg or yahoo answers because clicking anything will take of 50%. Giving college students cancer since 1998.

Person 1:Did you do Mastering Physics yet?

Person 2:Yeah it gave me cancer.

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!

Mastering Physics

A demonic website used by AP Phsyics high school teachers and college professors to rape any science student. Be prepared to lose all motivation to learn about science. Usually takes 4 hours, 2 hours if you cheat and use chegg or yahoo answers. Side effects include lack of sleep, losing hair, diarrhea, loss of time, and hysteria. Developed by students and MIT, yet it somehow spread to high school and colleges of obviously less intellect. If your teacher or professor assigns this, you might as well drop the class.

Dave: “ Hey, do we have mastering physics tonight?”
Alex: “ Yea, you might as well start now because you won’t be done until 2 A.M.”
Dave: “ Ok, first I’m going to go jump off a bridge.”

Mastering Engineering 

The number one cause for depression and suicide in engineering students. This program is so incompetent Satan wouldn't even use it to punish the damned because he wouldn't have the patience to input the 30 letter and number sequence to open the account. See also Mastering Chemistry, Mastering Physics, Mastering literally insert anything here. They're all equally crap.

"My professor assigned us Mastering Engineering this semester."
"That's rough buddy *ties you a noose*"
