A thursday night room cleaning to prep for a inspection friday morning that is required to go way beyond the point of clean to ridiculous things like no ice in your freezer, no water in your sink, no hygiene products in your shower. Most of the time you truly believe that someone woke up one morning, sat down with a pen and paper and just came up with a bunch of ridiculous things to look for in these "inspections". Basically Field day is just another tool used by Marine Corps leadership to piss off and demoralize Marines on a weekly basis.

A United States Marine Corps Field Day is very simple to explain. The bottom line is that it is done once a week and it is comprehensive. It is not a "Haze Ex" nor is it a way to "Punish the boots". It is a disciplinary tool to be used to instill a little self discipline so that rooms stay sanitary and Marines stay sharp.

Unfortunately, in the hands of inexperienced leaders, it becomes a haze ex. This was never the intent. When you think of all the discipline tools we have lost in the past 20 years, The "field day is one of the last things that makes a Marine different from a "service member". Never lose your traditions...

One day out of the week (generaly Thursday) when you are forced to clean everything in your room or squad bay like it was fresh out of the department store. Your work is then inspected by someone with higher rank (who's house has probably never been "field day'd") and it is this persons responsibility to find any spec of dust, wrinkled sheets, and/or pubic hair in and around the most ridiculous places you could imagine.
JJ: We have field day tonight.

Sean: What? Tell everyone I died man, I'm dipping out!

All that is holy and sacred in the Marine Corps. Thursday night when we all drink and laugh at the stupid boots running around the barracks with their mops and brooms.

Traditionally the drunker we get the more they clean, sometimes all night until the next morning's inspection. (Or until we pass out, which ever happens first) However in light of the large volume of pussies that have become Marines in recent years, "Field Day" as been regulated (actually raped) and turned into a pathetic half ass coast guard "general clean up."

The result of too many Marines crying and whinnying to their mothers about how unfair it is. (see also hazing & p.t. for more examples)

Now we must come up with new and more innovative ways of making the shower shoes suffer...

Me: "Hey sh*thead stop falling out of the run

Sh*thead: I can't help it, I'm too fat and lazy to keep up

Me: That's fine, I'll get it back during "Field Day" tonight

A day of fun and festivities to celebrate the birth of legends. Festivities may include a 21 beer salute, watching Django Unchained, a bar crawl, a traditional Jamaican lunch, Surf and Turf, and coitus.
Many people first experienced field day in elementary school as a day out of class to play games such as relay races, balloon toss, and wheel barrel races.

1. n. a silly adventure. 2. n. a day in elementary school where children do track and field. 3. v. (orig. US Coast Guard) to clean beyond the point of all logic.
1. Those kids had a field day with those squirt guns. 2. I love the shot put at field day. 3. You boys did not field day the head. You just cleaned it.
