Vietnamese Gen Z slang you will see online

Vietnamese Gen Z slang is mostly playful respellings, English borrowings and exaggerated reactions that live in comment sections, captions and group chats. If you see khum (a cute "no"), gét gô ("let's go") or u là trời ("OMG"), you are looking at it.

This guide focuses on what you will actually read online, which is different from what you will hear in a café. For the broader, all-ages list, start with Vietnamese slang: a friendly guide for beginners.

Why does online Vietnamese look so different?

Three habits shape it:

• Dropping diacritics. Typing all the tone marks is slow, so people often skip them and let context do the work.
• Shortening words. Common words shrink to one or two letters.
• Playing with sound. Words get respelled to sound cuter, funnier or more like English.

Combine all three and a simple sentence can become unrecognizable to a textbook learner.

The basic shortcuts

Before the true slang, learn these. They are used by almost everyone online, not just Gen Z:

• k, ko or hok = không (no, not)
• dc or đc = được (okay, can)
• j = gì (what)
• ny = người yêu (boyfriend or girlfriend)
• vs = với (with)
• bn = bao nhiêu (how much, how many)
• mk or mik = mình (I, me)

There is a fuller list in Vietnamese texting abbreviations: ko, dc, j and more.

Cute respellings

• Khum is a cute way to write không, mimicking a soft, babyish pronunciation. Khum biết means "Dunno." See khum, the cute way to say no.
• Hem and hông are other soft versions of không, with hông being genuinely common in Southern speech too.
• Iu stands for yêu (love). Iu quá is a cutesy "love it" or "love you."

English, Vietnamese-style

Gen Z borrows English freely and often respells it phonetically:

• Gét gô comes from "let's go," spelled the way it sounds to Vietnamese ears. It is used to hype something up.
• Chill means relaxed. Chill thôi means "Just chill."
• Flex means showing off.
• Crush means the person you like.
• Trend and viral are used as is, often with Vietnamese grammar around them.

Big reactions

Online reactions tend to be dramatic on purpose:

• U là trời is a playful "Oh my god," a stretched version of trời ơi.
• Xỉu means to faint. Xỉu ngang ("faint sideways") is the extra-dramatic version, used when something is too cute, too funny or too shocking.
• Ủa alo? combines "Huh?" with "Hello?" (as on the phone), meaning "Excuse me? Are you serious?"
• Đỉnh của chóp means top-tier, the very best.
• Ét ô ét spells out "SOS" in Vietnamese sounds and is used as a joking cry for help.

Mood and judgment words

• Toang means it has all gone wrong. A failed exam or a missed bus both qualify.
• Sống ảo describes living for social media and posing for photos.
• Mlem is an eating sound used for food that looks delicious, and sometimes for a person who looks attractive. Usage varies, and the second meaning is flirty, so be careful who you say it about.
• Trẻ trâu describes an immature kid acting tough online. It is an insult.

Is it okay to use Gen Z slang as a learner?

It is fine to understand it, and fun to drop in now and then with friends your age. A few cautions:

• Know your audience. Older relatives may find it confusing or silly.
• Expect change. Online slang moves fast. A term that is everywhere this year may feel dated next year.
• Do not overdo it. One well-placed gét gô sounds natural. Five in a row sounds like an ad.
• Avoid vulgar shortcuts. Some abbreviations stand for swear words. If you do not know what an abbreviation means, do not copy it.

Where you'll see it most

Gen Z slang shows up in comment sections on video platforms, in captions on Instagram-style posts and in group chats. Short-form video and cartoons are full of it too. In Duma Meow, the cats stick to everyday spoken Vietnamese like Ủa? and Trời ơi... đỉnh quá!, but the comments under any Vietnamese short video are a live classroom for this kind of slang.

A quick decoding exercise

Try reading this comment: "u là trời, đỉnh của chóp, gét gô!!" It means "Oh my god, this is the best, let's go!!" If you got it, you can already follow a lot of online Vietnamese.
