jacking race

Jacking off at a usual pace and then realizing that someone has pulled in the driveway or walked in the house and you now must race to finish the job before inevitable interruption, embarassment, and humility.

Johnny is jacking off and realizes Mommy is pulling in the driveway coming home from work. He must finish and we now have a jacking race.

Jacking off

When a young man or old man (can be both) get hard or also known as horny, they're penis starts to rise up. If they don't have anyone at the moment to help them with their needs, then they go to a private place such as the shower or their bed or also local wal-mart and go in a up and down motion on their penis. Causing them to feel the pleasure of having sex with a girl, or also feel the burn. When they reached their maximum pleasure a tasty substances called cum squirts out, and that is when he or she knows they are done jacking off.

Karma-jacking

The act of doing someone a favor, not for altruism, but in order to have the person in question owing you a favor.

I heard that she was going to NYC for the weekend, and that she didn't have a place to stay. I found a way of convincing her to stay at my friend's place. Now she's owing me a favor! This will be really useful when I visit Boston and want to meet her hot friends, ha ha ha. Karma-jacking FTW!
