Jack bag

n-Jack bag-a military issued sleeping bag that deployed soldiers sleep in and masturbate in before going to sleep at night thinking about their bitch back home or due to the absence of woman. THis sleeping bag can become very foul throughout the course of a deployment. So be weary next time you shop for a used sleeping bag at the Army surplus store.

Friend #1: "Hey if we are going camping I need to borrow a sleeping bag"

Friend #2: "Yeah I have one you can borrow. I slept in this one when I was deployed to Afghanistan"

Friend #1: "FUCK NO!!!! I aint sleepin' in no Jack bag}!!!!"

Jackwagon

A useless piece of equipment, usually military, used to refer to a mule-drawn freight wagon which had been pieced together from dicarded or substandard parts, and subject to frequent breakdowns. Jackwagons typically were good for only one or two uses, then abandoned or discarded along roadsides and in ditches, and were often re-cannibalized to create new jackwagons.
