Comes from a Hank Williams Jr. song called Attitude Adjustment, song makes more sence than the lyrics.
The act of correcting a person for their inapropriet actions, for stepping over the line, to show your dominance over them, or to let them know their place with you. Similar to correctiing a dog on a slip collar. It involves a brief correction, typically involving something other than your fist or hand, like a stick, belt, pipe, tire iron, or cane. This is not a full on beating, asskicking, or fist fight, just one or two hits with the tool of choice to let them know they don't want anymore.
Father: That piece of shit son in law treats your sister like shit, and everyone else for that matter.

Son: Come on pop I'll get the tire iron from my truck and well give him an attitude adjustment.

Here is part of the song from Hank Williams Jr. - Now I've got this big old Brother-in-law
And me and him just never did get along
Cause he just wasn't treating my sister nice.
He got drunk one night and started and beating me up
And I went and got a tire tool out of my truck
And straightened him out as cold as a block of ice.
It was an attitude adjustment and it'll work every time.
An attitude adjustment-I made him see the light.
Now he says I'm his kind of man,
He comes around me with his hat in his hand
It was an attitude adjustment; I cured his family pride.

An adjustable wrench or crescent wrench is a type of wrench that is made to be adjustable to several different sizes, allowing the user to carry one wrench rather than several. Under certain circumstances, an adjustable wrench may be considered a suitable replacement for a hammer, at which point it is then known as an adjustable hammer.

Adjustment Disorder is a deep set fear of not only change but of leaving the house, going on a date, sleeping at a friends home, moving, among other normal everyday things. Adjustment disorder is caused by little things that internally scar us although we may not know when it happens. For example:

I am at home all day for a few weeks and then when I go out I feel like I am guilty of something or like I won't have a home to go back to.

I sleep over at a friends house and I have to go home halfway through the night because I am afraid to be away from home too long.

I start working at a new job and I feel like I am going to be fired for something little like dropping a pencil because I am attached to my old job.

Adjustment Disorder doesn't make a lot of sense to someone who doesn't have it. It is a difficult thing to cope with. It makes us afraid of random things that no one else even gives a second thought.
My Adjustment Disorder keeps me from dating again because I am bone chillingly afraid that I will get hurt again after being single for a year.

The nightstick police and rent-a-cops carry with them, mainly to make them feel big and tough, but sometimes to use it on pickpockets or dope-smoking teenagers.

(ECONOMICS) adjusted for the time of year the data refer to.

Economic statistics are often reported as rates of change from month to month, or quarter to quarter. However, some months, such as November and December, have very high retail sales, while May through September have very high home sales. For this reason, data is sometimes "seasonally adjusted" to offset ordinary seasonal variations.

The US Federal Reserve System reports changes in GDP from quarter to quarter in annualized form; so, for example, during the last quarter of 2004, US GDP was (about) $3,044.6 billion. But it was reported as an annualized (and seasonally adjusted) $11734.9. If you divide that by 4 you get 2957.8, which reflects the fact that the Fed shaved 86.8 billion off its estimate of economic activity for 2004Q4 and reallocated it to Q1 & Q2.

The reason the Fed (and everyone else) does this is to measure economic change separately from the usual seasonal change in business activity.
BILL: Hey! This data on GDP growth is way different from that data.

ANNA: That's because one set of data is seasonally adjusted. The Fed tweaked the numbers so economic growth from quarter to quarter reflects changing economic conditions, instead of ordinary yearly cycles.

BILL: You mean it's not an evil plot?

ANNA: It's an evil plot to make you forget about Christmas shopping season and labor day white sales.

BILL: Gasp! You mean the Fed is behind the War on Christmas?????
