9 Slang Words for How We Talk Online

Someone ends a message with "ngl," or answers your idea with one word, "bet," and you wonder whether they're being warm, blunt, or both. Chat slang packs a lot of tone into very few letters, and the tone is exactly what a quick search doesn't tell you.

This guide covers nine words and abbreviations people use in messages. Each one is tied to a dictionary or a named source where one exists, and the guide includes a cheat-sheet table and a section on using slang in a message on Japansdates.

A note on "new": some of these only reached dictionaries recently, some have been in texting for years, and two have no dictionary entry at all. Newness in slang is slippery because dictionaries tend to record a word after it has already been in use for a while. The table says which is which.

Words That Soften or Sharpen a Line

Written messages have no face to soften them, so people borrow short words to do that job. These four are the usual picks.

Ngl

Short for "not gonna lie," and the Cambridge Dictionary lists it as informal, used to admit something a little awkward or to soften a criticism. "Ngl, I fell asleep during the second half" is honest and light at once. In a Japansdates message, it can take the edge off a candid comment, and paired with something kind, it sounds like care rather than criticism.

Tbh

Dictionary.com defines it as short for "to be honest," used to introduce a frank statement or an opinion. It works like a small drumroll. On Japansdates, it's a handy way to share a preference without sounding blunt, as in "tbh, I prefer long messages." Use it once in a message, since a second one starts to sound like a habit.

No Cap

As slang for "no lie," a way of saying you aren't exaggerating. It fits small, surprising claims, like "no cap, that sandwich was enormous." In a Japansdates chat, a big claim wearing it can raise an eyebrow, so save it for light topics. Stack it on every claim, and it stops meaning anything.

Lowkey

People use it to mean "somewhat" or "quietly," as in "lowkey excited about the weekend." On Japansdates, it keeps an eager line sounding relaxed.

Words for Reacting

Not every message needs a full answer. These three words are for the times you want to react and move on.

Bet

Dictionary.com lists "bet" as slang for "yes" or "okay," used to agree with a suggestion or confirm arrangements. "Want to trade playlists?" "Bet." It's brisk by design, and a one-word "bet" on Japansdates can read as curt, so a few extra words keep it friendly. Pair it with a detail, such as a time or a topic, and it sounds warmer.

Smh

Short for "shaking my head," and it signals disapproval, disbelief, or disappointment. It's most comfortable aimed at yourself ("typed my own name wrong, smh"). Said about a situation rather than a person, it reads as shared frustration. On Japansdates, pointing it at the other person tends to sound harsher than intended.

Delulu

Cambridge Dictionary added "delulu" in August 2025. It's a shortened, usually humorous form of "delusional," and it describes believing something that isn't true, often by choice. Humor about your own hopes can make a Japansdates bio more fun to read.

Words About Reaching Out and Waiting

These two sit at either end of a message: sending one, and waiting to hear back.

DM

Merriam-Webster lists "DM" as a verb: to send someone a direct message, especially on social media. "I'll DM you the link" is plain enough. On Japansdates, the closest equivalent is a private message inside a conversation.

Left on Read

Plainly informal, and not a dictionary entry: it means a message was seen, on an app that shows a "read" marker, but not answered. It carries a small sting, so it's worth remembering that people log in at different times, and if a Japansdates message goes unanswered for a while, that usually tells you less than it feels like.

The Cheat Sheet for Japansdates Chats

Here are the nine in one place for your next Japansdates chat:

The example lines are ours, written to show the words in use, and none comes from a Japansdates member.

Reading Tone Without a Voice

Slang is one clue to tone. Message length is another, and so are punctuation and whether the message asks you anything. A short reply with a question usually invites more, while a short reply without one may simply be a short reply. Reading the whole message, and not one word of it, keeps a lot of misunderstandings from starting on Japansdates.

Using Slang in a Message on Japansdates

Fun as it is, slang is also a way to be misunderstood. A few habits help in a first message on Japansdates:

• A word that's clear to one reader can puzzle another, so plain words travel further

• If you use one slang word, keep the rest of the sentence plain, so the meaning survives even if the word doesn't

• Ask your question directly, and don't let a slang word stand in for it

• Reread a line before sending and cut anything you'd have to explain, since a word that needs "(that means...)" after it is a word to swap for a plain one

Keep it simple. Several tools on Japansdates help with the planning part. Icebreakers are opening messages that come as templates, and you can send one to several members at once, so you start from ready-made wording. Japansdates supports conversations with members who have opted to receive messages or shown prior interest, so choose recipients whose profiles held your attention for a reason. Email letters on Japansdates give you room to explain a term if you're unsure the other person knows it.

One Word That Doesn't Need Decoding

"Verified" is a word you can take at face value on Japansdates. Voluntary identity verification is available through a recognized third-party provider, and members who complete it receive a verification badge. A badge is a note that a check was done. Reading the person behind the profile is a separate job. Age verification works differently: when our systems detect signals that a member may be under 18, it is triggered, and that member must complete it to keep using Japansdates. Our guide to how identity checks work on Japansdates goes into more detail.

Where Slang Stops Being Useful on Japansdates

Dictionaries add words after they've spread, so some of today's slang will sound dated within a year. That's normal on Japansdates and everywhere else, and it's no reason to avoid slang entirely. It's a reason to hold it loosely and to keep a plain version of the sentence ready. Hold slang loosely.
