Thought to have originated on TOTSE this is a common reply to a very long post. It means Too long/Didn't read.
Person 1: Here is my thought on the meaning of life...(Goes on for another 1000 words

Too Long; Didn't Read

Literally translates to: That was too long to read.
Really translates to: I'm too lazy to read the entirety of what you said, but I still want to say something.

Now, instead of just dropping capitals the modern internet communicator also drops tiresome reading! The time savings will be incredible.

Person A: AGH... It burns!

"too long; didn't read."
1. The inability to accept, understand or pay attention to information when not separated by a header.
2. The ability to arbitrarily read 400 small posts but not a long one.
3. A sign of ADD or lack of reading capability.
4. A very cheap response and an indication of lack of wit.
5. 90% of the time: A lie.
6. A desperate attempt at a comeback used by people who just can't think of one.
7. Usually used by people who've been torn apart verbally but want one last attempt at looking witty.
8. Total failure at #7.
7. A sign that, not only is someone too lazy and stupid to read but, clearly, too lazy and stupid to even type out four words indicating such.
9. Collect every "tl,dr" post online, and you'll have a good estimate of the number of lazy idiots on Earth, who currently have Internet access.
10. Should really be:
"Too Lazy, Don't Read."
or,
".....I got nut'n!"
~ ME:
.....Therefore you suck fabulous donkey shit cock.
~ "Smart Troll" Not Used To Being Beaten:
*yawn* tl;dr
~ Me:
...Right, well, as believable as that is, you've got time. Just sound the bigger words out. Now I can see why your friends say you're so "smart".

Stands for "too long, didn't read". It can be interpreted in different ways depending on the context.

1. When responding as a first post, and only as a first post, on a thread, it means the OP's post was so long and unimportant or uninteresting that the user deemed it unworthy of his/her time. If the topic really is unimportant and uninteresting, and long enough to need more than a minute to be read and understood, the user ends up looking clever, though on some communities the user may end up looking like a troll or a lazy bum.

2. When responding during an already ongoing discussion where others haven't used the term, it means the user is trying to diminish the topic's importance or entertainment value, but considering that such a strategy won't work in a discussion where people are actually participating, the user ends up looking like a dipshit.

3. When responding with it during an argument, it means that the user in question wants to win the argument by stating that what the other person is saying is so worthless it's not worth reading. But by evading the argument instead of confronting it directly, it becomes obvious that the user got owned.
1.

- someguy1: *posts a very large and boring flow chart about people in facebook*
- User: tl;dr
- others: I second that.

*on a community where users actually like these things*
- User: tl;dr
- others: If you think it's too long then GTFO, retard.

2.

- User: tl;dr
*some ignore dipshit and continue discussion, some others tell the dipshit to GTFO, everyone will report the post to mods*

3.

- someguy1: *totally proves that he's right and/or User is wrong*
- User: tl; dr
- others: hahah he got pwned and he's chickening out, what a pussy!

Literally: Too long; didn't read

Possible subtext: You make a very good point to which I have no sensible or comical response thefore I will claim it was too long for me to manage reading in order that I might still have the last word (or slightly confusing modern acronym)

"Too Long; Didn't Read" - a shining example of the sweeping Attention Deficit Disorder pandemic that seems to have embraced our society. Usually said by people who a) have never read a book, b) have no logical retort, c) want an easy laugh, or any combination of the three. Not to be confused with "TMS;DU", meaning "Too Many Syllables; Don't Understand", which is likely how some of you reading this feel about this definition.
Spanky - "I find it hilarious that any definition of TL;DR condeming those who use it as uneducated morons, are the ones receiving more thumbs down - just like this one probably will - even though they are the most accurate. That just further proves that people - especially kids - have a consistantly dwindling attention span, most likely indirectly proportional to the amount of media and entertainment devices we feel the need to constantly plug ourselves into."
Spunky - "... TL;DR"
Spanky - "Are you sure it wasn't TMS;DU?"
Spunky - "... l0zz0rs, pwned."
