(v) jacking off in your mind
"Whoa this hot girl walked by, and i started to mindjack!"

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.
