Another fun phrase with similar etymology is "pulling out all the stops". It comes from church organs, where the stops are all of the levers that can change the timbre

Ohhhh this makes sense too! I actually have a pipe organ in my garage so I know exactly what you’re talking about!

I wish I owned a garage. Or a house. Or a fucking shed. Need to start smaller. Maybe food first. We'll work our way into it

Going "balls out" refers to governors on steam engines which used centrifugal force on a pair of balls to regulate the speed of the engine. At full speed the balls were out at the maximum.

That refers to noted hippie Mad Jack McMadd, whose balls were so big he used to trip on them when he got high.

Have you ever accidentally stood on a ball (football/dodgeball) and tripped? If you have you may have an idea where the expression comes from. You trip really hard.

So is the term "grounded" and I genuinely wonder what parents used to say to their misbehaved children before airplane terminology was commonplace.

Not to be confused of course with "balls deep", which is exactly what it sounds like

It's when your shaft is so damn deep that you can only barely make out your ball amidst the shaggy rough entanglement. Courses like Oakmont Country Club, Ko'olau, and Pinehurst are some examples that can challenge even top golfers.

Silly. It's from hitting a baseball so far that the balls deep in the bushes

Of course we still don't have an agreed upon standard for how deep balls deep actually is.

3

It used to be relative but the French have an underground chamber that has very precisely controlled environmental conditions to avoid shrinkage, ensuring exact depth of balls. It’s actually quite scientific.

"Just under the wire" has a similar aviation lineage. According to my dad some WWII fighter planes had a wire attached across the throttle lever slot to mark the point that was considered "full throttle". The wire was breakable, so a pilot in a desperate situation could push the throttle farther forward if necessary, but I think there was a danger of blowing up the engine. So being just under the wire meant not quite past that point.

TIL you can increase engine power by mixing water into the fuel.

You can also increase speed by not using any propellers or moving parts. At supersonic speeds you capture the air, compress it into a chamber than hit it with a spark and blow the fucker up. That's how a ramjet engine works. China just made one that uses pulse like combustions in a engine that's only about a foot wide, and maybe 13 feet long. Speeds up to mach 4.. or 5000km/h (3100mph) at about 65,000 feet.

It needs to be injected into the air charge with the best atomization you can manage for best results.

The Corsair had water injection as a WEP, I forget by what mechanism it worked but it could make that big ol' Pratt & Whitney eat its own guts for more horsepower.

Thanks, that's a lot more than my sketchy memory of what my dad told me (WWII pilot). Might not be where "under the wire" came from but it's fascinating.

You will hear Apollo astronauts occasionally say "all balls" or "five balls." After performing maneuvers, they would check their trajectory by taking fixes on stars using the telescope/sextant, this data would be fed into the guidance computer, which would compute their deviation from their intended course. If they were perfectly on their intended course, it would display a variation of 00000. "All balls." Perfectly accurate.

Kind of like 'having one's balls in a vice'. It actually refers to the old days when ball bearings were made by hand. It was tedious work and the pressure to make ball bearings for the burgeoning industrial revolution was intense. They were cut out of metal and then polished smooth, secured in a vice. Hence, 'having your balls in a vice' meant being under intense pressure.

To expand, it is referring to pushing the gas pedal to the (metal) floor when racing.

Vulgar in linguistics refers to street usage instead of formal. See also Classic Latin vs Vulgar Latin.

Another fun one is that in the phrase "three sheets to the wind" Sheets do not refer to the sails as many believe, they actually refer to the ropes that tie down the sales. So you lose a sheet, the sail becomes less predictable. If you lost 3 sails I think you'd just be dead in the water most times, not stumbling about

Patrick O'Brian has a bunch of opinions about these. "The devil to pay" was spreading pitch on, or paying, the hard-to-reach seam between deck and hull called the devil. At loggerheads means fighting with the long poles with a hot iron ball on the end , or loggerheads, used to heat pitch.

You may be thinking of "balls out" which refers to centrifugal regulators that are usually used on steam engines.

As do many airplanes, in fact Cessna-style plunger throttle controls are relatively unusual.

The knobs on airplane throttles or thrust levers are also seldom spherical; it has happened but most are cylindrical. There's a whole section in FAR 23 that talks about how they have to be oriented in the cockpit, the shape and color of the knobs/handles etc. so pilots can tell them apart at a glance/by feel. For instance, when you first climb into a Cessna Skyhawk the position of the flap lever in front of the copilot's left knee feels kind of strange, almost everything is conveniently placed for the pilot, but the flaps are way over there. law requires the flap control to be to the right of the cockpit centerline, the gear lever must be to the left, but a Skyhawk has fixed gear.

You often hear steam engineers say "put the throttle on the ceiling" meaning apply full power. Diesel engineers will refer to "notch 8" as the highest power setting.

My mom worked for the railroad - she was the first trains woman to become a superconductor.

I guess it makes more sense than slamming your testicals against the wall.

In a way relating to human anatomy that has caused me to remove this phrase from my usage in recent years (because I worried how others would take it) the balls=testicles actually always made sense to me, but I'm not going to explain it.

However, now that I know what the most literal interpretation of the phrase actually is, I can feel safe using it again!
