Names for common things we see every day that people may not know the name to.

The ridge that runs along the bottom of your scrotum (well, mine, anyway) is called a “raphe.”

Also, that adorable pursed-lip pouty thing that French gamines do is called a “moue.”

You named yours!?! :eek:

Also called a number sign.

There are also fraction and division slashes, which may or may not be different, depending on the font.

There are also comparable widths of spaces:
Thin space
En space
Em space

If there isn’t, how about patibulum?

The squiggly lines in Microsoft Word that indicate you might have misspelled a word are called ‘wavy underlines.’

How very goulish. It would certainly work and it’s seasonally appropriate.

A group of cats is a clowder.
A group of ravens is an unkindness.

When you play a piano, the string is hit by a hammer, technically making it a percussion instrument.

A tool to punch out holes is a knockout punch.

And I am printing this all out for my next scrabble game.

The tool for opening the bungs on a 55 gallon drum is called a bung toolor bung wrench. In the old days they were made out of brass or bronze, to prevent sparks and the explosions that could follow if the bung of something flammable wasn’t cooperating.

Now they can be made out of aluminum or plastic, and bungs are a little more standardized; so you don’t usually need one of the big old monstrosities with multiple protuberances to fit different kinds of bungs. Which is a pity. The first bung tool I ever used was one that I couldn’t pick up without thinking “blunt instrument.” I knew that the healing had started when I could use it without thinking of my ex-husband. You know, just in passing.

Actually, that was a joke. A woman in the 15th century, Juliana Berners, Prioress of Sopewell, wrote a book on hunting, and it was basically serious, but she slipped in some jokes. There was a chapter of collective nouns for animals that were hunted, like a herd of deer, which were things hunters might want to know, but after the serious animals on the list, she included a clowder (clutter) of cats, a shrewdness of apes, a baren [sic] of mules, a murder of crows, and then she went on to groups of people: a superfluity of nuns, a fighting of beggars, a lying of pardoners, an incredibility of cuckolds, among many others. It’s very funny.

A lot of people didn’t get that it was a joke, though, and some of the terms actually entered the language.
Here’s mine: what people call “camouflage,” clothing, the Army calls BDUs, or "Battle Dress Uniform. It’s not the standard anymore, though, and now the Army uses ACUs (the minecraft-looking stuff); ACU stands for “Army Combat Uniform.” The uniform that soldiers in Iraq wore was called DCUs, or “Desert Camouflage Uniform”; it had a pattern print like regular camouflage, but it sandy colors. There was also briefly a DBDU “Desert Battle Dress Uniform,” (the one with the sand and rocks) that was used in the Persian Gulf war, but the DCU was found to be more effective.

zombie or no

Those grooves on the side of the highway are called Rumble Strips. (or sleeper lines)

A Torah is a handwritten scroll of the first five books of the Hebrew bible. A printed version, which may be in any language, and is often in the language of the land where its printed, and Hebrew side by side, is called a “chumash.” The “ch” is like the ch in “Chanukah.”

It’s unusual to hear the word “yarmulke” anymore. Almost everyone calls the little head caps “kippah” pl-“kippot,” which is the Hebrew word.

The dust or shavings (often mental shavings) removed from an object by a cutting or grinding tool is called swarf (also used for space junk, apparently), unless it made of diamond, in which case it is bort (I guess bort isn’t that common, though).
