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?"

An "up jack" is when you ejaculate into your own face and rub the semen into your nostrils.
You can up jack someone else by grabbing their penis and causing them to ejaculate into their face, at which time you rub the semen into their nostrils.
