What Does 彩虹屁 Mean? The Chinese Slang for Over-the-Top Praise

If a Chinese friend reads your post and comments 别吹彩虹屁了, they are not talking about the weather—or about your stomach. 彩虹屁 (cǎihóngpì) literally means “rainbow fart,” and it is one of the most colorful words in modern Chinese slang. It describes praise so lavish, creative and over-the-top that it sounds almost magical.

The picture behind it is simple: you admire someone so much that even their farts come out as rainbows. In this guide, you will learn what 彩虹屁 means, where it came from, how to use it in real sentences, and how it compares with other Chinese words for praise and flattery.

Key takeaways

• 彩虹屁 means extravagant, imaginative praise—usually playful, not insulting.
• It began in Chinese fan culture (饭圈, fànquān) around 2017.
• The usual verb is 吹: 吹彩虹屁 means “to shower someone with praise.”
• It is different from 拍马屁 (pāi mǎpì), which means flattering someone to get something.
• It is casual. Use it with friends and online, not in formal writing.

What does 彩虹屁 mean?

The word has two parts:

The joke works on two levels. First, it imagines someone so perfect that even their farts are beautiful. Second, 屁 is already part of older words for flattery, such as 拍马屁, so “a rainbow-colored fart” sounds like a prettier, more artistic kind of flattery.

In English, you might call it gushing, glowing praise or laying it on thick. The difference is that 彩虹屁 is usually lighthearted. When people say it, they are often smiling.

Where did 彩虹屁 come from?

Fan culture (2017)

The word was born in Chinese 饭圈 (fànquān, “fan circles”), the online communities of fans who follow pop idols and actors. Around 2017, fans began competing to write the most beautiful compliments about their idols on social media. A simple photo of an idol drinking water could receive hundreds of comments like “连喝水都这么好看！”—“Even drinking water looks this good!” Many people believe this style of fan writing was inspired by Korean fan culture.

Fans needed a name for this kind of praise. Because it was so flowery that even something as unattractive as a fart would be described as a rainbow, they called it 彩虹屁.

From fans to everyone (2018–2019)

In 2018, the word spread far beyond fan groups when fans of the popular web drama Guardian (《镇魂》) filled the internet with creative compliments and memes about its stars. In 2019, China Daily chose 彩虹屁 as one of its “words of the day,” translating it literally as “rainbow fart.”

That same year, 夸夸群 (kuākuā qún, “praise groups”) went viral on Chinese university campuses. In these group chats, anyone could post a problem—“I failed my exam”—and the other members would shower them with praise: “Failing shows you have room to grow!” Praise groups made the idea of 彩虹屁 part of everyday humor.

彩虹屁 today

Today, almost anyone can be the target of a 彩虹屁: friends, coworkers, pets, a delicious bowl of noodles, a city, even a brand. People still use it for idols, but it is now a normal part of casual Chinese.

How to use 彩虹屁

Common phrases

The verb 吹 (chuī) means “to blow.” It also appears in 吹牛 (chuīniú, “to brag”), so in Chinese, both bragging and praising involve a lot of blowing air.

What does a 彩虹屁 sound like?

A good 彩虹屁 is creative and exaggerated. These phrases often appear in fan comments and friendly praise:

The pattern 连……都…… (“even … ”) is the secret ingredient of many 彩虹屁. It takes something ordinary—drinking water, getting angry, yawning—and turns it into proof of perfection.

彩虹屁 vs. 拍马屁 and other praise words

Chinese has many words for praise, and they are not all equally positive.

The key difference is motive. 拍马屁 means flattering someone with power—a boss, a teacher, a rich client—because you want something. It sounds fake. 彩虹屁 is usually open and enthusiastic. Everyone knows it is exaggerated, and that is part of the fun.

Why “patting a horse”? A popular explanation goes back to the horse-riding peoples of northern China. When two riders met, one might pat the other's horse on the rump and praise it—“What a fine horse!”—even if the horse was quite ordinary. Over time, “patting the horse's bottom” came to mean flattering someone to please them.

Why is 彩虹屁 so popular?

Traditional Chinese manners value 谦虚 (qiānxū, “modesty”). When someone praises you, the classic polite reply is not “thank you” but 哪里哪里 (nǎlǐ nǎlǐ)—literally “where? where?”—meaning “Oh, not at all.”

彩虹屁 gives people a fun way around this. Because the praise is so exaggerated that it is half a joke, the person receiving it does not need to feel embarrassed, and the person giving it does not sound like a flatterer. It lets friends say “you're amazing” in a way that feels light and natural.

How to reply to 彩虹屁

When should you use 彩虹屁?

Use 彩虹屁 in relaxed situations: group chats, social media comments, conversations with friends and classmates, or when talking about fans and idols. It sounds young, funny and friendly.

Avoid it in formal writing, business emails and conversations with people you have just met. The word contains 屁, which is a bit crude. In formal situations, use 称赞, 赞美 or 高度评价 (gāodù píngjià, “to speak highly of”).
