Jack

Jack is the kind of person who is smart, and quiet. Typically good with music, and very good looking. The kind of person, who is almost PAINFULLY oblivious to people who have a crush on them. The kind of person who in the middle of a conversation, will crack an amazing joke, but says it so quietly that only a person sitting next to him would hear, and laugh. Overall, a very sweet, and wonderful person.

“Who wrote that awesome essay about Bach’s life?”
“Oh, that was Jack. Duh.”

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.
