Using Chinese internet slang and memes in brand copy: when it lands and when it dies
Here's the short version: Chinese internet slang works in brand copy only when your brand already lives where the slang was born, when the joke is still alive, and when you can stop using it the week it dies. Otherwise it reads like a foreign brand wearing a borrowed hat. Slang in brand copy is a loan with a very short term, not an asset.
Every few months a client asks me to "make the copy more online." What they usually mean is: find a trending phrase and drop it into the headline. I understand the temptation. Slang is the fastest way to sound like a local. It is also the fastest way to sound like a marketer who read a listicle on Monday and shipped on Tuesday.
Why slang is tempting, and why it is different from ordinary copy
Chinese internet slang is not decoration. It is a membership signal. Take yyds, the initialism of 永远的神 ("forever the god"). It spread out of gaming communities into everyday praise, according to China Daily's explainer. Using it tells readers you know the room. Using it badly tells them you only know the word.
That is the whole game. The phrase carries tone, tribe, and timing. Translating it, or lifting it without the tone, keeps only the surface.
When slang lands
- Your audience is native to the platform. Bilibili, Douyin comment sections, and Red threads reward in-group language because the audience already speaks it.
- The brand is playful by nature. Snacks, drinks, games, and youth fashion can carry a joke. A private bank cannot.
- You use the phrase once, at the right moment. One well-placed line beats five stacked memes.
- Someone native reviews it the day you ship. Not the agency account lead. A person who uses the platform daily.
When it dies
A meme has a half-life, and it is measured in weeks, not quarters. Some commentators argue slang simply fades as usage drops, so a term can lose its charm before it ever becomes a liability. For a brand that means your print run, packaging, or six-month campaign can outlive the joke it was built on. Print slang on a box and you have put a date stamp on a product that has to sell for two years.
It also dies when the brand is the wrong speaker. A phrase can be charming from a peer and grating from a company. Luckin Coffee, for example, filed trademarks combining "yyds" with its product names, per Jiemian's reporting. It is a native coffee chain with a young, app-first audience and a habit of playing with internet culture. Copying that move from a heritage European brand with a founder's portrait on the label is a different thing entirely.
The regulatory edge nobody mentions
Slang is not only a taste question. In 2014 the broadcast regulator then known as SAPPRFT issued a notice barring arbitrary changes to Chinese characters and the insertion of internet slang or foreign words into idioms, covering broadcast content and advertising, as summarized by That's Mags. The rule targets TV and broadcast ads, not a Red post, and the regulator has since been restructured. But it shows the direction of official attitudes. State media has also criticized popular slang, including yyds, as a kind of "language disorder", as Vice reported. Wordplay on idioms in a paid ad is where I would check with a local legal reviewer before launch.
A working rule of thumb
| Placement | Slang risk | My call |
|---|---|---|
| Social replies and comments | Low, easy to retire | Fine, if the person replying is native |
| Short-video captions and hooks | Medium | Use lightly, refresh weekly |
| Paid ads and broadcast | Higher, with idiom-wordplay limits | Plain copy, legal review for any wordplay |
| Packaging, signage, long-lived assets | High, cannot be retired | Avoid. Use timeless language |
| Brand name and slogan | Highest | Never |
What I do instead of chasing memes
- Listen first. Read the comment sections in your category for a few weeks. Learn which phrases people use about your product, not the ones trending in general.
- Borrow the register, not the word. Short sentences, self-deprecation, and understatement travel longer than any single phrase. This is the same logic behind transcreation rather than translation.
- Let creators carry the slang. A KOC can say it without risk because they own the voice. The brand account should stay a step behind.
- Set an expiry. Every slang-based asset gets a retire date at the time it is written.
Bottom line
Slang is a cheap way to look local and an expensive way to look late. Use it in places you can change tomorrow, let native voices own it, and keep your permanent assets in plain, confident language. The brands that sound most at home in China rarely sound like they are trying.
If you are working out the voice for a Greater China or Southeast Asia launch and want a second read on the copy, that is the work I do. Reach out. And for the broader context, read selling to China's Gen Z.
