TL;DR
TL;DR is short for too long; didn’t read. It began as something you said about someone else’s wall of text, and it now mostly appears at the top of a post, written by the person who wrote the post. Those are opposite jobs, both are in use, and there is no emoji for either.

What it actually means
The original is an insult with the receipt attached. You posted a wall of text; somebody replied tl;dr, meaning they got far enough to measure it and no further. Oxford Learner’s still records that sense first — used in response to a blog or online post, to show disapproval — and it is the reading that makes the grammar work. Too long; didn’t read is a confession about reading. The semicolon is doing real work: it is two clauses, cause and effect, not a label.
Then it flipped. Writers started putting TL;DR at the top of their own posts, followed by the one-line version, and the phrase became a courtesy — here is the short one, in case you would rather not. Said about your own writing it is strictly nonsense, since you plainly did read it, having typed it. Nobody minds. Merriam-Webster covered it in Words We’re Watching while it was still a candidate and now carries a full entry; Cambridge, Dictionary.com and Oxford Learner’s all list both the disapproval and the summary.
The reversal has not settled, which is why the live results for it are not dictionaries. The top organic result is an r/etymology thread asking how TL;DR became a synonym for summary, and next to it sits one from r/NoStupidQuestions asking whether people are using it wrong. They are both right. A word that can be a complaint about your writing or a kindness in your writing, depending only on who typed it, is a word doing two jobs with one spelling — and there is a third, quieter one: on Linux, tldr is a command that prints the short version of a manual page.
When you’d send it
The six-paragraph Slack message with a one-line summary on topThe summary is the message. The rest is evidence.- Scrolling to the bottom for a TL;DR that is not thereBetrayed by a stranger.
- Writing your own TL;DR and making it almost as longFour sentences. The ambition got you again.
- “tl;dr?” as the entire replyRude, efficient, and fair maybe a third of the time.
- Realising the TL;DR disagrees with the postOne of them is lying and it is usually the short one.
Why there’s no emoji for it
The keyboard has nothing for the shape of this. It can show you a document, an arrow and a scissors, but the request is not about paper or direction or cutting — it is about wanting the conclusion without the argument. And because the phrase does two opposite jobs, anything you send has to pick one, which is exactly the part the words do not pick.
The long thing itself. Sending it hands the problem back instead of asking for the short version.
Scroll, keep going, below — a direction, and the one request TL;DR is not making. The point is to not travel the distance.
Writing, which is the opposite end. This asks for more words, which is how the trouble started.
Bored. That is an insult about the content, where tl;dr is a complaint about the length — a long thriller still gets a tl;dr.
Cut it down. Closest in intent, but it reads as a coupon or a haircut, and it tells the writer to do the work rather than asking for the result.
Announces a long one is coming. Perfect opposite: the thread is the crime, not the remedy.
The Vigil icon draws a document with four long lines, an arrow down, and two short ones. Nothing is deleted and nothing is crossed out — the long version is still sitting there, intact, above its own summary. That is the honest picture of what TL;DR does now. It does not replace the wall of text. It sits on top of it and admits the wall exists.

What does TL;DR mean?
Too long; didn’t read. It is either a reply telling someone their post was too long to read, or a label a writer puts on their own one-line summary so you can skip the rest. Both uses are current and they mean opposite things.
Is it TLDR or TL;DR?
Both are correct and dictionaries list them together. TL;DR with the semicolon is the original, because it is two clauses — too long, therefore didn’t read. TLDR is the flattened everyday spelling, and tl;dr in lowercase is common on forums.
Is there a TL;DR emoji?
No. 📄 is the long document, ⬇️ is a direction, and ✂️ reads as a haircut. Vigil’s TL;DR icon — four long lines, an arrow, two short ones — is free as a Slack or Discord emoji, an iMessage or WhatsApp sticker, or an SVG.
Is saying tl;dr rude?
It depends which way it points. Written by the author at the top of their own post it is a courtesy. Sent as a reply to someone else’s it means you did not read what they wrote, which is usually received exactly as it sounds.
