"Thả thính": the Vietnamese slang for flirting

Thả thính is Vietnamese slang for flirting, especially dropping hints or cheesy lines to see if someone bites. Literally, it means "dropping bait," and it's used about everything from a playful comment under a selfie to an outright pickup line.

Say it roughly as "tah TINH," with a question-like dip on "thả" and a rising tone on "thính."

Where the phrase comes from

The image comes from fishing. Thả means to drop or release, and thính is toasted rice bran or powder that people sprinkle into the water as bait to attract fish. So "thả thính" paints a picture of someone scattering bait and waiting to see who swims over.

It's a vivid metaphor, and that's part of why it caught on so strongly with young Vietnamese people on social media.

How thả thính is used

Here are the patterns you'll hear most:

• "Đang thả thính à?" "Are you flirting?" Often teasing a friend who just posted something suspiciously romantic.
• "Thả thính ai đấy?" "Who are you flirting with?" (Northern style, with đấy)
• "Thính này thơm quá." "This bait smells great," meaning "that's a good line."
• "Dính thính rồi." "Got hooked." Said when someone falls for the flirting.
• "Cẩn thận dính thính." "Careful you don't get hooked."

Thính on its own can also mean a flirty line or caption. People share lists of "câu thả thính" (flirting lines), often built on puns and wordplay.

Dính thính: getting hooked

The natural partner to thả thính is dính thính, literally "sticking to the bait." If your friend has been chatting nonstop with someone who flirted with them, you might say "Dính thính rồi nhé!" ("You're hooked now!"). It's teasing and lighthearted.

What a typical thả thính line looks like

Vietnamese flirting lines often play with sounds and double meanings, much like English pickup lines. Many work on wordplay that doesn't translate cleanly, which is half the fun. You'll often see:

• Compliments framed as a joke
• Lines comparing someone to coffee, sunshine or the weather
• Puns on someone's name

They're mostly meant to be funny and slightly cringe-worthy rather than smooth. Posting a deliberately cheesy line as a caption is a classic way to thả thính to no one in particular.

Thả thính vs. tán tỉnh

Tán tỉnh is the more standard word for flirting or courting. It's neutral and can be used in more serious contexts. Thả thính is the slang version, more casual and playful, and often implies throwing out hints rather than directly pursuing someone.

A rough comparison:

• Tán tỉnh: courting or flirting directly
• Thả thính: dropping playful hints or bait, often publicly
• Crush: the person you like (borrowed from English)

If the flirting works and you end up dating, that person becomes your người yêu, which texters shorten to "ny." Our guide to what NY means in Vietnamese texting covers that vocabulary.

Where you'll see it

Thả thính is everywhere online: comments on photos, captions with heart emojis, messages on dating apps and memes about "professional bait droppers." Some people joke about being "thánh thả thính" ("a saint of flirting," meaning someone who flirts with everyone).

It also appears in songs, TV shows and ads aimed at younger audiences, which helped make it mainstream.

Is it okay to use?

Yes, in casual settings. Thả thính is playful and not vulgar. Use it with friends or in social media banter. In formal conversations, or with someone who might take it as a real romantic advance when you don't mean it that way, choose your words more carefully.

As with flirting in any language, read the room. What's fun with a close friend can feel awkward with a coworker.

If a Vietnamese friend accuses you of thả thính, laugh and reply "đâu có!" ("no way!"), which works whether it's true or not.
