Jumping Jackoff

What a perfect 4th of July!
After webcamming with Sandra most of the morning, I spent the rest of the holiday in the backyard pool -


Is there such a thing as a "Jumping Jackoff"? I know there's an excercise called the "Jumping Jack" and I'm thinking for some reason that if you do a jumping jack off the diving board, it's called a "jumping jackoff". I used to do them when I was 10 years old or so.
But that just as well may have been something I made up as a kid.

At any rate, jumping jackoffs hurt a lot more than I remember (in the private area) and I don't recommend them for guys over the age of 10.
