Literally - Too long ; Didn't read

A phrase typed in response to a blog, forum post, or other form of online media to express either that the submission of another user was either needlessly long or wordy or that the reader has a complete lack of interest in the subject matter.

Contrary to the belief held by those who experience mild to moderate butthurt due to having made submissions that either nobody cared about enough to read or were much longer than necessary for the sole purpose of condescension or self-exaltation, replying to media with "tl;dr" does not necessarily indicate substandard intelligence or an attention deficit.

This definition is a good example of a post in which replying "tl;dr" to would be appropriate.
H.Horse: "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.

Joe: tl;dr

H.Horse: 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.

Joe: No, I'm not a moron. I'm just indicating that you're pompous and arrogant and nobody cares about your novel. Also, you spelled "condemning" and "consistently" wrong.

Short for "Too Long; Didn't Read"

Originally intended for when someone makes a point in an arguement/discussion and the intended target of the point cannot be bothered to read the lengthy comment. However, it has been overused and brutally raped of it's meaning due to people being incapable of responding with an intellectual/witty remark. Now most commonly means "Your arguement is so sound and accurate that I can find no flaw to point out. However I do not wish to look like an uneducated fool, and so I shall instead respond as if you are the ignorant one for posting an in depth comment of such length that it would imply too much effort to read." Ironically, a large number of people would be likely to comment TL;DR to this definition if given the opportunity, thereby showing that they fall into the category of people to whom this applies
Original intended use:
An individual, most likely a "nerd", posts a comment of excessive length on a subject, unnecessarily expanding on points rather than getting to the point, thereby deserving of the response
TL;DR

Recent most common usage:
A point is made in which the commenter backs up their claims with facts and evidence, only to receive the response
TL;DR

Too long, don't read

or

Too long, didn't read

A post, comment and/or reply that is (perhaps) gratuitously, (over)indulgently long.
.... and so A happened to B, and C got the bad end if it really, but it's not as simple as that...

tl; dr

(expounding of above point)

OR

...omg, sorry but, tl; dr! :) I *do* agree with what you said about Y being in front of Z, though...

This is shorthand for:

"Hey guys, look at me, I have nothing to contribute to the discussion, but I'll just let you know how ignorant and stupid I am."

Commonly used on internet forums.
Poster 1: *Tries to initiate a discussion*

Poster 2: tl;dr

Person 1: Hey, here's an idea - if you have nothing to say, don't post!

Too long: Didn't read

The bastian of the stupid and lazy. Only those of no intelligance would bother to use this, as if you are unable to read a post, then you should not bother even replying to begin with.
