J.R. Masterman

A public school in Philadelphia known to be in the top 100 schools in the country. #1 school in the state. Obviously, it is a magnet school but despite this it has very low funds from the city. There is so much competition for enterance that kids who get 95% on their entrance exams are put on the waiting list and often denied admission. Kids there are allowed to graduate in 11th grade (they don't get a graduation but they do get a diploma if they want it in 11th).

You go to J.R. Masterman? Wow.

Masterlock

Poorly made shit for shit lock. There are several ways to unlock it without picks. It's possible and extremely easy to make a shim out of a soda can and unlock it.

Jack thought his bike was secure with his Masterlock, but the next day someone guessed his combination in 3 minutes and rode off into the sunset.

mastermind

A master mind sees it before it comes
A master mind before he goes to war he count his one's
A master mind every thing planned out perfect
A master mind sleeps at night real easy
A master mind cuz every thing is by the book
A master mind never do a thing irrational lives for ever his tales are classical

Masterjobbing

Masturbating while someone else gives you a handjob. Note: In order to not be gay, assistant's hand needs to be on top.

Your sexy roommate is masturbating, you lend him a hand thus performing the masterjobbing maneuver.
