Mastylock 

When ones main hand becomes stiff and starts to twitch out of control. Chronic masturbation is the leading cause of this common teenage male disease.

Symptoms:
Sudden urge to relieve one self
Bulging fore-arm muscle, with inverse proportion to the opposite fore-arm.

If one finds another person/persons with "Mastylock", it is highly recommended to stand back and then state clearly who currently has it and what it is.

Warning: Staring at someones "Mastylock" can sometimes cause the looker to catch "Mastylock", depending on ones sexuality.

"Oh my god Kieran has Mastylock! Its when someone masturbates so much thier hand locks up!"

Jac is a faggot.

Matlock 

Someone who picks and picks at your very believable story until you break down and confess the truth.

or someone who points out something obvious to everyone else.

"Dude, how did your Mom find out you were'nt staying over at my house?"
"She gave me the Matlock."

"Man, it sure is raining."
"Thanks, Matlock."

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.
