Cracking Jack

The act of jerking off (typically a man), especially to the point of orgasm.

Originates from the term "jacking off" as well as the similarity of the "cracking" sound from performing it and the opening of usually alcoholic beverage bottles.
It is also a popular perversion of "cracker jack", the brand of caramel corn.

Roommate: "You two were so loud last night! I heard you cracking jack so loud I couldn't get to sleep!"

mind jack

When a show you're watching is so good it's the equivalent of your mind masturbating. A mind jack. (From the verb 'to jack off)

I don't know how Ugly Betty and Lost manage it, but every week when I'm watching...It's just a mind jack.

Speaker Jack

Most commonly occurring in a committed relationship or close proximity roommate situation. It is the act of putting ones own show/music/etc on speakers before the other domestic resident can put theirs on speakers, thus forcing them to use headphones. Most relevant when the other party had theirs on speakers first, and due to an interruption they paused/muted their sound, and upon cessation of the interruption, the first party puts their audible content on speakers.

- WTF? I was watching DS:9!
