jack it up

Briefly and rapidly masturbating a quasi-erect penis (or "semi") after foreplay leading to partner sex. In this usage the goal is not to masturbate to orgasm, but merely to get the penis stiff enough to penetrate vagina or anus under the assumption that the erection will stay sufficient throughout intercourse aka fucking, presumably leading to a successful climax (orgasm).

"I had to jack it up a little before I could go in, but I was afraid she'd think it was kind of gay, or that I didn't love her."

"Naw, man, you do what you gotta do. Go ahead and get it up a little more. If Dorothy has a problem with that, then why doesn't she use HER hand?"

hi-jack

1. To take over by force
2. To replace someone's home page to some crappy search engine that they would never have used and still won't even if they can't get it off their computer.

Home Search Assistant totally fucking hi-jacked me! But I still h4x0red its ass.

Jack reacharound

The feeling experienced of having your time wasted after watching a movie as bad as jack reacher.

Watching jack reacher was a real jack reacharound. That movie was so bad a reacharound would have been better.
