Coming from a military background we use a lot of acronyms. Basically these are words that we chop up and only use the first letter of each word to describe a word or a saying.We call these diddies,which is basically away or a form of remembering the word or phrase. For example
OFP This would relate to a marine who does whatever he wants when he wants. That marine there is on his Own F***ing program!
From this point that guy is about to receive and ASS Chewing, or he is about to be Locked The F*** on which means exactly that.
These are just some of a lot of military jargon. I could have a conversation with one of my military buddies in front of the entire class and probably no one in the class would understand any of what was being talked about. Another for instance a bathroom is called a Head, doors and Windows are called portholes, a marine with glasses is wearing BCs or if he is a funny looking marine with glasses we say he has birth controls on. A female marine is called a WM woman marine, IF your are in a recon unit or some type of infantry/victor unit which is all men, you would see and talk even more jacked up than regular marines because its all men and you would not half to worry about what is said in front of females. We call women marines that are in the field bag nasties which has been abolished now days but infantry or real marines still say it. These are all forms of military people communicating with each, civilians or people not affiliated with the military would be lost in the sauce.
