Okay, so the other day, I was scrolling through some forums, and I kept seeing “421” pop up in different threads. I was like, “What the heck is that?” It wasn’t in a techy context, so I knew it wasn’t some error code. Curiosity got the best of me.
Digging Around
My first step, naturally, was to fire up Google. I typed in “what does 421 mean” and started browsing.
- I saw some stuff about HTTP status codes, but that didn’t seem to fit. 421 is “Misdirected Request,” which is all techy server stuff, it didn’t apply to this situation.
- I checked on, but the definitions there were all over the place. Nothing really clicked.
- Finally, I stumbled upon some discussions mentioning it was more of a dating or relationship context.
The “Aha!” Moment
It seems like a special code for Chinese Valentine’s Day. It’s a romantic, straightforward way to send love to a person.

Putting it All Together
So, basically, I learned that if someone sends you “421”, maybe you should consider sending them some love back, LOL.
It was a fun little investigation! I love how the internet can turn up these random, unexpected meanings for numbers and phrases. Now, every time I see “421,” I’ll have this little inside knowledge of the love code.
