How Humans Use Symbols to Communicate Faster
In this not-so-brave new world where speed and brevity often outdo formality, humans have become gurus of symbolic communication. Whether it’s texting under time pressure, posting on social media, or navigating digital spaces with limited character counts, we’ve developed clever ways to say more with less.
This isn’t a new phenomenon Back in the 90s, personal pagers were the original shorthand devices. People sent pages to others using numeric codes like 143 to say “I love you” and 07734 to cheekily upside-down reference to “hello.” Now we fast forward to 2025, and emojis have taken over as the new visual language where a peach 🍑 doesn’t just mean fruit, and an eggplant 🍆 might raise eyebrows for reasons far beyond gardening.
These substitutions aren’t just playful, they’re efficient, expressive, and often culturally rich. They allow us to convey emotion, humor, sarcasm, and even entire narratives with just a few characters or images. From numbers and acronyms to emojis and internet slang, these representations form a kind of futuristic hieroglyphic language that many intuitively understand.
Hey, let’s dive into this fascinating realm of symbolic shorthand. Below is a not-so-comprehensive list of examples of this new shorthand, that I am writing about. Some of these are nostalgic, others are current, and yet all are terrific in their ability to compress meaning into minimal form.

I Don’t Even Comprehend the New “6 7”Thing
Google Gemini Says: The phrase “6 7” is a viral internet meme and slang term that generally has no fixed meaning and is used as an interjection or an inside joke among Gen Alpha and Gen Z. It was notably named Dictionary.com’s 2025 “Word of the Year” precisely because of its widespread, nonsensical nature.
Ultimately, “6 7” is a prime example of “brain rot” slang—digital media considered to be of poor quality but popular among young people for its playful, absurd nature and the sense of community it fosters.
