Mastersoak 

Guided masturbation. Where a man grabs his own shaft as if he were to choke the chicken. But a woman takes the mans hand/wrist and does the motion for them. Thus, not masturbation.

Tony: Bro, so what did you and Alice do last night?

Samuel: Dude, all we did was mastersoak.

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.
