applying lubricant to the penis, then rubbing it slowly up and down while viewing images of attractive woman naked or engaging in sex acts. In time, the rhythmic movement will lead to a build-up in excitement. At this point, your sister and her best mate will walk in. It'll be too late to stop and a sticky whitish fluid will shoot out onto your computer screen. The girls will close the door and you will be left in a state of profound shame.

Causes Pleasure and Anger. The pleasurable part is pre-ejaculation. The Anger part is post-ejaculation. This is the part where the man becomes mad at himself for wasting 30 minutes of his time. The world suddenly becomes clear and the chemical imbalance is one again balanced. Too bad no man learns this lesson and history repeats itself.

Giving the 'Private' a dishonorable discharge.
by Private P. Nuss August 16, 2004
Jacking off is when you take your hand, and grab your cock like there is no freaking tomorrow, make sure you have a firm grip! Move your hand up and down and up and down again and again, if you do it right and long enough, you'll ejaculate all over. Sometimes you want to eat some, so you do. I do it like 3 times a day, and sometimes I'm dry by night, but I love it so much, too bad I can't reach down to give myself a blowjob!
I was jacking off in the bathroom at school and it went "thump, thump, thump" until it just all came out and I was relieved that I let go of my seed.
