Catch-22 I always wanted to know this!
This phrase, meaning a situation where one bureaucratic regulation is dependent on another, which in turn is dependent on the first, derives from the 1961 novel of the same name by Joseph Heller:
Yossarian looked at him soberly and tried another approach. "Is Orr crazy?"
"He sure is," Doc Daneeka said.
"Can you ground him?"
"I sure can. But first he has to ask me to. That's part of the rule."
"Then why doesn't he ask you to?"
"Because he's crazy," Doc Daneeka said. "He has to be crazy to keep flying combat missions after all the close calls he's had. Sure, I can ground Orr. But first he has to ask me to."
"That's all he has to do to be grounded?"
"That's all. Let him ask me."
"And then you can ground him?" Yossarian asked.
"No. Then I can't ground him."
"You mean there's a catch?"
"Sure there's a catch," Doc Daneeka replied. "Catch-22. Anyone who wants to get out of combat duty isn't really crazy."
There was only one catch and that was Catch-22, which specified that a concern for one's own safety in the face of dangers that were real and immediate was the process of a rational mind. Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn't, but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to. Yossarian was moved very deeply by the absolute simplicity of this clause of Catch-22 and let out a respectful whistle.
"That's some catch, that Catch-22," he observed.
"It's the best there is," Doc Daneeka agreed.
Heller originally titled his novel Catch-18, but at the request of his publisher changed it. Leon Uris had just published Mila-18 and the publisher did not want confusion between the two books.
Brownie Points
This term derives from the girl scouts. That organization had (has?) a system of points that the girls would accumulate toward advancement.
The phrase entered the general language from WWII in military slang. Uniforms, the army's tendency to have soldiers do things that seemed silly and child-like, and evocation of brown-nose all contributed to the popularity of the phrase.
I worked for the GS and I never knew this!!
Mind Your P's & Q's I always wanted to know this, too!
The phrase dates to the late 18th century--at least 1779. The exact origin is unknown, but several competing hypotheses seem to be the most likely.
The first is that it derives from the phrase p and q which was an abbreviation for prime quality. This English dialectical term dates to the 17th century. So to mind your p's and q's would mean to be exacting in detail and ensure high quality.
The second is that it refers to difficulty children had in learning to distinguish between the letters p and q, being mirror images of one another. To learn one's p's and q's is a phrase meaning to learn one's letters is first recorded around 1830--somewhat later but not impossible as the origin. Often this explanation is identified with printers and distinguish between a p and a q in type, but the early use exclusively deals with children, not printing.
The third, first suggested by Farmer and Henley at the turn of the 20th century, is that the phrase comes from the practice of maintaining a tally in pubs and taverns. Marks under column P, for pint, or Q, for quart, would be made on a blackboard. To tell a bartender to mind his Ps and Qs would be to tell him to mind his own business and get back to work.
Another commonly suggested explanation is that it is a variation on mind your pleases and thank yous, a plea for gentility and manners. There is no evidence to support this, nor does the please and thank you phrase appear anywhere except in explanations of the Ps and Qs origin.
The last is from the world of printing. Typesetters had to be skilled in reading letters backward, as the blocks of type would have mirror images of the letters. The lower-case letters p and q were particularly difficult to distinguish because they are mirrors of one another and located in bins next to one another. Typesetters had to be particularly careful not to confuse the two.
Which is the correct one is anybody's guess (except the fourth which is certainly false). I favor the second explanation, but that is just a personal preference.
Phat
Phat is another word that frequently is given an acronymic origin. The exact acronym varies with the telling, Pretty Hot And Tempting, Pretty Hips And Thighs, and Pussy Hips Ass Tits have all been suggested. There is no evidence supporting any acronymic origin.
Rather, phat is most likely simply a slang respelling of fat. Such respellings are common in slang. And fat has a long history of meaning rich, abundant, or desirable. Fat has been used this way in English since the early 17th century, and in other languages for far longer. The specific sexual connotation of phat is likely just a specialization of the general meaning. Some suggest it may be a clipping of emphatic. Again, there is no evidence for this last, but at least it's more plausible than any of the acronymic origins.
Phat is also older than you might think. It has been a staple of African American slang since at least 1963.
Piccaninny
This word is a West Indian variation on the Spanish pequeno or pequenino meaning diminutive or tiny one. It entered English around 1687. Applied to small, black children, originally it was a term of endearment but is considered offensive today.
Picnic
Internet lore (and perhaps folklore prior to the internet) has the origin of this word as lynching party for blacks in the American South, originally deriving from the phrase pick an nigger. This is absolutely incorrect. The word's origins have no racial overtones whatsoever.
In actuality, the word derives from the French pique-nique, meaning the same thing as it does in English--an outing that includes food. Pique is either a reference to a leisurely style of eating (as in "pick at your food") or it's a reference to selective delicacies chosen for the outing. Nique is a nonsense syllable chosen to rhyme. The word appears in English as early as 1748 in reference to picnics in Germany. The word did not gain widespread use in Britain until c. 1800.
BUUUUUUUT...
Grandfather Clause
A grandfather clause is one that allows someone who previously had the right to do something to continue doing it even though the law forbids it to others. For example, when I turned nineteen, the state of New Jersey allowed me to drink alcohol. Later than year, they raised the drinking age to twenty-one, but since I was already of legal drinking age, I was grandfathered and could continue to legally consume alcoholic beverages. But why grandfather?
The term comes from discriminatory practices of certain Southern states against blacks. In the late 19th and early 20th centuries, some Southern states had laws requiring payment of a poll tax or taking of a literacy test before one could vote. The poor and illiterate were denied the right to vote. This was race-neutral except for clauses in the state constitutions that exempted someone from poll taxes or literacy tests if their grandfather had had the right to vote. This meant that virtually all whites, whose grandfathers could vote before the imposition of these laws, were allowed to vote, while most blacks were denied the right to vote. Over the years, the term has lost the racial stigma and no longer connotes racial bias.
The term grandfather clause dates to 1900. The verb form, to grandfather, is more recent, dating to 1972.
