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.
Oh man, I up jacked so much last night that everything still smells like my seed.
