The first time I saw tldr, I was scrolling through a long comment on a forum. It went on forever. Just when I was about to give up, I saw one short line at the bottom: “tldr: it’s not worth it.” I laughed, felt relieved, and instantly understood why people use it.
Since then, I’ve seen tldr everywhere texts, social media posts, Reddit threads, even work chats. If you’ve ever felt confused or curious about this tiny but powerful internet term, you’re not alone. Let’s break it down in a simple, friendly way.
Quick Answer:
TLDR means “Too Long; Didn’t Read,” and it’s used to summarize long text or say something was too long to read.
What Does TLDR Mean in Text?
TLDR stands for “Too Long; Didn’t Read.”
It’s a popular texting abbreviation and online chat meaning used when a message, post, or article feels very long.
In plain English, tldr is a shortcut. It tells people, “Here’s the short version,” or “I didn’t read all of that.”
People use it for two main reasons:
- To summarize long content
- To politely (or jokingly) say something is too long
Simple example:
“tldr: he was late because his alarm didn’t go off.”
In this case, the long story came first, and tldr introduces the quick summary.
Bold takeaway: TLDR means “too long; didn’t read” and is used to give or request a short summary of long content.
