What is a military cadence?

Factual Questions
1

I was reading a humor list about some military thing or other, and came across, "the following is not to be used in a “cadence”?

Is that when you’re marching and start chanting?

Precisely. Sometimes called a “Jodey call.”

Thanks. Mods, if you want you can close this, since it’s answered. Unless there are any other questions.
