"Jodie Calls" or "Cadences" are sung by the military while marching in rank. All branches of the military sing jodies -- even the Marine Corps.
They are used to keep the troopies in time, and -- more importantly -- as a morale-builder.
When I went through Basic Training at Ft. Jackson in 1985, the New Army sensitivity hadn't quite made it down to us, as a result, we still sang the older jodies. Vulgar, tasteless, obscene and scatological doesn't quite cover it.
As Army recruits, we were firmly informed that we had two missions in life. The first of these was to kill people. The second was to break things. Those were our duties.
As a result, our jodies revolved around killing the enemy, killing Jody (the civilian at home who was topping your girl while you were in uniform), dying ourselves if we screwed up; about blowing things up, burning them down; loud, lewd ruminations about women, their morals and anatomical details...
Y'all get the picture. Not exactly Politically correct, but we were a bunch of piss-and-vinegar 18 year-olds who were training to become United States aRmy soldiers. We were not the Rover Scouts, and if you couldn't handle harsh language and vivid imagery, then you didn't need to be anywhere near where we were marching.
I bring this up, because apparently the USMC upper echelon has lost their ever-loving minds.
They seem to have developed an organization-wide wedgie concerning a song sung by a Marine, for the amusement of other Marines.
Rumour has it that some high-level marine-type officers are looking for an excuse to bust these kids.
Folks, any USMC officer of LTC (that's Lieutenant-Colonel, I'm Army, stuff your LtCol) rank or higher was probably indoctrinated into the U.S. military at the same time that I was.
Any officer of LTC rank or higher sang the same damned jodies that I did at the time.
If I chanted "Bodies, Bleeding Bodies", "Napalm Sticks To Kids", and "Up Jumped The Monkey" then those very officers did, too, if not worse ones.
Any officer that breaks it off in those kids for singing a song that is considerably tamer than the cadences that officer sang when said officer was the same age as those kids is one hypocritical bastard.
And you can quote me on that one.
