In 1899, people were walking around shouting ‘23’ at each other and laughing, and confused reporters were writing articles trying to figure out what it meant.

For millennials, like me: 1337 means “LEET” which is short for “Elite”.
Also for geeky Gen X
Y35!
i installed a kali linux vm and nmap, wireshark, tcpdump, and metasploit cuz i wanna be teh 1337 h4x0r i wanted to be when i was a 15 year old in 2001
Had a friend who wrote his french oral presentation out in 1337, he was allowed notes but not the word for word presentation. He showed the teacher beforehand, she said that’s fine, looks like gibberish.
I did that too, but back then it was called Backtrack Linux. I bought a special Atheros chipset WiFi card for my laptop’s PCMCIA slot. The built-in 802.11b WiFi card worked under Linux but only by using the Windows ME driver in NDISWrapper, which didn’t support promiscuous mode.
The Atheros chipsets could be configured (by flashing the firmware with a blob I got from a BBS, if I recall) to capture the traffic from nearby wireless networks. In particular, I wanted to pick up the signal from when a device first connects. There was a bug in Windows XP that could cause the WiFi to drop briefly, then promptly reconnect. By triggering that bug over and over I could capture a lot of reconnect packets in a short time frame.
Then I’d save the data to a big file and pipe it to Aircrack and extract the Wired Equivalent Privacy password.
I was a 1337 H4XX0|2 B-)
Tap for spoiler
Well, that’s how the tutorial said it would work anyway. I actually never could get enough packets captured. The signal strength was too low
Same, but I was 15 like 15 years later lol
I’m confused as to where you fit in the Millennial demographic for you to have not known this already
It seems, I’m on the older side.
Sorry, what? I’m a millennial, this is common knowledge for anyone who played a videogame in the last quarter century.
I was going to say, I think the perpetuation of leetspeak and most of its use falls squarely into the millennial generation’s early 90s into the early 2000s.

What the h311 is wrong with you? Us millennials invented 1337!
Nope. Source: am gen X.
Yep I think pops here has this one, us Millennials grew up with leet speak, it already was a thing in the 80s.
Yeah it was common on BBSes late 80s at least. Also am gen X.
That’s the first time anyone called me pops! NOW I feel old!

Ragebait. Millenials are like 40 and have back pain.

I can confirm you can in fact get back pain before the age of 40
Batman can confirm too.
