Jack Duke

Masturbating while taking a dump, especially if done out of neccessity due to lack of a more appropriate venue.

This camping trip's been a bear, I've had no time to myself. Things got so bad I had to take a Jack Duke in my friend's RV.

ninja jack

The ninja jack. The act of jacking off silently (quickly in most cases) and without those around you knowing that you had even done so.

Usually refers to jacking off while someone is talking on the phone (I.e. a girlfriend calls and you rub one out while she talks about something random).

Girl: "Hey, so anyways my day blah blah blah"
Guy: "yup, sounds good"
Guy::touching himself/finishes::
Girl: "So- what do you think?"
Guy: "Sounds like a plan. We meet at your parents house for dinner tomorrow night"

Ninja jack successful.

Girl: "What's wrong- you sound winded"

Almost.

Flat Jack

A Flat Jack is a square of breaded processed chicken that can be heated up in a toaster instead of an oven, making it a quick and convenient lunch option or snack food.
It's like a chicken nugget that is the size and shape of a Pop-Tart.

Hey man, I'm hungry, but I dont want to heat up the oven or turn on the stove for something small. What do I do?

Oh, no problem. Stick a couple Flat Jacks in the toaster and you're good to go dude.

Thanks brah
