Fast Jack

The act of masturbating very quickly when given a narrow window of time. Usually occurs when there is a brief period of time when one can masturbate without being seen by others.

I got a lap dance from that hot chick at the strip club and then I went over in the corner and had a fast jack while no one was looking.

Simple Jack'd

To be ridiculously stupid and genius all at the same time.

-Doing homework ahead of time for one class, then turning it in to another, you just Simple Jack'd yourself
-Trying to scare someone back, when the person you scare is yourself, you just got Simple Jack'd.
-It can be applied to almost anything.

1.) To go for a walk in in the woods, aka Mother Nature, pull off the trail somewhere, proceed to masturbait and then continue on your hike. 2.) To jack off in the woods while camping, fishing, hunting, etc.
3.) Applies to females as well. Simply the act of masturbaiting in the woods.

Joe went for a long walk in the woods to clear his mind. About halfway through the hike he stepped behind a large tree to nature jack and then continued about his stroll.
