Union Jack

Commonly used but incorrect name for the Union Flag of the United Kingdom.

It should only be called the Union Jack when being flown at sea.

When flying from a flagpole on land "Union Flag"

When flying from part of a boat at sea "Union Jack"

Yank tourist "Ooooh look, the Union Jack".

Infinitely more intelligent Brit "Pillock, it's called the Union Flag".

jack shack

Usually specific to soldiers, or other people who are forced to live in close proximity for long periods of time without either sexual activity or privacy, a jack shack is a small shack made out of blankets, ponchos or poncho liners that is erected so that the builder can masturbate in relative peace. It is often explained away as a means to block light, or provide privacy to change, despite being erected almost exclusively around one's sleeping quarters.

He had only been in Iraq for a week, but he had already built an intricate and comfortable jack shack.

jacking off

Jacking off is after you play withself and can't hold back the pleasure and excitement you just created playing with your self, then you cum.

I love to play with myself while looking at pics of girls on the internet. I can do this for hours and really love it. I like to put rubber bands around my balls, they make them bounce around alot while jacking and feeels real good to me. I like girls to watch me play with myself also , mostly they just laugh, especially when I can't hold back any more and finish playing by jacking off. Watching me cum, they laugh alot , I love it.
