Coffee nicknames origins

I did my best to find the origins to each of the slang words mentioned here. Don’t blame me if it’s not correct. You can send me a message here, and I’ll be happy to add that in, if it’s true.


The phrase “cup of joe” has multiple meanings. According to one theory, it was named after a Navy general named Joe who told sailors, “No more booze, only coffee from here on out.” According to a second theory, Joe is a common man’s name, and coffee is his drink. A third theory, based on our penchant for shortening words, contends that “joe” is an abbreviated version of the words “java” and “mocha” combined. Read our article to learn more about how it all began.


Java is neither a particular form of coffee drink nor a method of making it––in fact, the word derives from the history of coffee. The Dutch brought coffee to Southeast Asia in the 1600s and planted coffee plants in places like Bali and Sumatra, as well as on a small Indonesian island called Java.

When coffee first became popular in the 1800s, the Indonesian island of Java was the primary source of the world’s coffee. So it’s only normal that a mug of hot coffee became known as java. Today, the word “java” has become a common term for coffee, and it no longer applies solely to coffee from the Indonesian island of Java.

Mud or Dirt

“Mud” and “dirt” are fairly obvious nicknames. Coffee, mud and dirt are all brown, but the slang is most likely derived from bad coffee that is heavy with grounds. If anyone refers to the coffee you made them as “shit” or “dirt,” you should brush up on your barista skills. Although Turkish or cowboy coffee is basically boiling coffee with water so it can turn into a mud like drink.

Dirty Bean Water

Dirty bean water is mostly used for unfiltered coffee, but if the “dirty” element is removed, it may be used for any coffee.

But technically speaking, coffee is a fruit, so it’s more of a dirty juice than dirty bean 🙂

Bean Juice

Although you can’t juice a coffee bean like a lemon, you can still produce an amazing cup of bean juice or technical term would be extraction.

Oddly enough, there are some companies actually selling coffee bean juice

Dark Water

Not to confuse you with the 2005 film, or the 2019 film Dark Waters, or the coffee company. Can’t find anything on its origin.

High Octane

Some individuals drink coffee just for the energizing effect that caffeine has on their bloodstream. Caffeine may raise your heart rate and blood pressure, giving you a jittery or jumpy sensation. Nonetheless, caffeine addicts will be queuing for their fourth or fifth cup of high octane before lunchtime.


You might not come across this slang term for coffee, unless you’re reading this article and decided to try it. Just put on some eye glasses with a pen protector sleeve. But, you can play it cool and sound overly smart and be a bit pretentious.

Cupped Lightning

This one is mainly used by people who are very sensitive to caffeine. Mostly because drinking a cup of coffee to them feels like being hit by lightning. Both mess with your heart, that’s for sure. Although this term isn’t that popular and becoming extinct.


This is another another little perplexing coffee slang word. When you hear someone refer to their coffee as a “Baltimore,” it most likely indicates it’s half regular and half decaf. This may be a good compromise for folks who want a coffee later in the day but don’t want to risk staying up late at night due to caffeine. This, like many other coffee phrases, is not exactly clear how it came to be. However, it’s generally safe to conclude that it all started in Baltimore.


This one was used in the introduction. This phrase is so very British, since it is British, it definitely refers to a cup of tea rather than a cup of coffee. So, do it like the Brits, they drink so much tea that I am assuming this was meant for those who consume as much coffee like the Brits do their tea.

Morning Brew

This is a term that is often used to refer to coffee. Since it basically simply explains what you’re doing (brewing) and when you’re doing it (morning). It does, however, have certain witchy undertones. Witches like brewing their own beverages. And coffee does, indeed, touch that enchanted spell-like sweet spot.

There’s two words for coffee “java” and “mocha”. In the late 1800s, some folks couldn’t determine which one sounded more calm, so they invented the clipped compound jamocha.

It has the sound of a ja-joke-a.

Over time, the name was tainted by the word “moke,” and the derivation “jamoke” was employed as an insult.

Jamocha, on the other hand, was an innocent, though repetitive, name for coffee when it first entered use.


Arbuckles became a slang name for coffee among cowboys. It was the name of the coffee brand that was utilized on the path. Arbuckles was known as cowboy coffee because it was sold in patented airtight one-pound bags of beans in a solid wooden box of 100 packages that kept the coffee fresh.

Coffee terms based on appearance

Other slang terms for coffee would be how they appear, just like “mud”, so no origin story here:

  • Ink
  • Oil
  • Sludge


Yes, yes. When you say let’s go to Starbucks, you literally mean, “lets grab a cup of coffee.
