What is "Có mà mơ"? Why Gen Z Uses This Phrase All Over TikTok
Can you believe it: what is "có mà mơ" - this question has been asked by countless generations of Vietnamese people when they first hear this phrase that has "existed" in Vietnamese culture since forever, passed down through generations, from parents in the old days to Gen Z today who still use it... enthusiastically!
"Có mà mơ" - this phrase appears everywhere, from family arguments at home to "super fierce" exchanges on social media. But why does such a simple phrase have such incredible viral power? And why, when someone comes up with an idea that's "a bit too much," do we reflexively blurt out... "Có mà mơ!"?
Let's explore this "immortal" phrase with CHUS, because the story behind it is more interesting than you think!
What is "Có mà mơ"?
1. From everyday conversation
What does "có mà mơ" mean? This is how Vietnamese people express very strong denial, meaning something like "Don't even think about it!", "Not gonna happen!" or "No way!". This slang originates from natural everyday speech, shortened from the full phrase "Có cái gì mà mơ" (What is there to dream about) to a more concise and "razor-sharp" version.
Unlike new trends emerging on social media, "có mà mơ" doesn't have any specific origin. It naturally formed and developed over time, becoming part of the DNA of Vietnamese daily language. Many people, when first asked what "có mà mơ" means, often answer immediately without thinking - because it has become instinctive.

2. The real meaning
From the beginning until now, "có mà mơ" has been used to express disagreement or rejection in an "extremely clear" way. It's like saying: "As if! Keep dreaming!", but it sounds... cuter.
Vietnamese people use this phrase to react to unacceptable suggestions, unrealistic predictions, or promises they doubt. This is the "ultimate weapon" in our rejection arsenal! When someone wonders what "có mà mơ" means, they're actually trying to understand how an extremely effective "communication tool" works.
3. "Immortality" across generations
From grandparents' generation, parents to today's Gen Z, "có mà mơ" is still passed down and widely used. This proves that some phrases don't need to go viral on TikTok to survive - they're already part of the culture!

The phrase has transformed from everyday speech into a versatile communication tool used everywhere from real life to social media. Today's young generation not only knows how to use it but also creates many variations, surprising those who don't yet know what it means with its diversity in usage.
What makes this phrase so "hot"?
- Sounds much more "sharp" than the usual polite refusal
- Creates a sense of "having personality" even when just refusing normally
- Can be used in any situation: both refusing and mocking
- Saves time on long explanations while still being clear enough
The phrase goes viral strongly on TikTok and social media platforms
Diverse applications, Vietnamese style
Throw away the so-called "long rejection reasons"! Vietnamese people have found a reaction formula that's both concise and "extremely fierce":
1. When genuinely refusing
Your friend asks to borrow your brand new phone for a week-long trip? "Có mà mơ!" is the natural reaction when you find this request... a bit much.
Real example:
- A: "Let me borrow your new motorbike tonight, I have a date."
- B: "No way! I still need it for work."
2. When doubting unrealistic things
See someone predicting something unrealistic? Hear a promise you don't believe? This phrase is the Vietnamese way of expressing doubt... politely. This is also when many people better understand its meaning in the context of showing skepticism.
Typical situation:
- A: "It'll stop raining tonight, let's go get street food."
- B: "In your dreams! Look at those dark clouds and you think it'll stop raining."
3. When exaggerating
A normal situation but seems a bit "dramatic"? A plan that sounds wild? "Definitely not happening" - the Vietnamese way of turning everyday situations into discussion topics.
Instead of explaining at length "I can't do that", "This can't happen", or "You're saying something unrealistic", Vietnamese people just say briefly: "Có mà mơ". Short, concise, everyone understands!
Flexible use in all situations from refusing to showing personality
Why does this phrase "survive" so strongly?
1. A type of "economical" language
This phrase is essentially a super economical language. It doesn't need long explanations - just these words are enough to express a clear attitude. This is how Vietnamese people communicate in a "less but quality" style - few words but full of power. When asked about its meaning, this is the key point to emphasize.
2. Creates a sense of "having character" when used
This phrase isn't bland like normal speech, but carries a bit of "personality", a bit of attitude. When using it, speakers feel they're expressing their personal opinion clearly and decisively.
It's like when you say "forget it" instead of "I don't want to" - it feels much more "characteristic", right?

3. Instant emotional connection
The era of fast communication is the era of immediacy. No need for long explanations, just this phrase is enough for others to immediately understand your attitude. It helps create quick connection and understanding between speaker and listener.
4. Flexible application in daily life
Vietnamese people now don't just use this phrase for rejection, but have flexibly applied it to many situations:
- Someone brags they'll wake up early to exercise? "Yeah right."
- Your friend says they'll stop eating snacks to lose weight? "Not gonna happen."
- Your crush promises to text regularly? "Sure they will, they'll probably disappear for three days."
Daily life is full of promises and plans, and this phrase is how Vietnamese people express reality... humorously.
