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*

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.

An internet abbrviation for: Too long; didn't read. Only something a lethargic and obviously illiterate person would use.

This is an alternative way to understand tl;dr

So usually it's a response to a long-winded written explanation that someone posts online. But it can also be used as a brief summary of something at the top of a post for readers who don't have time to go through the whole thing

For example: My trip to Europe

tl;dr - I went to Europe, I ate cheese, danced with beautiful woman, hooked up with a man and had a unexpected boat trip.

On 21 January I got the itch to travel, so I spontaneously booked a trip to Europe... insert rest of post
Friend who got a job interview: I’m very excited. Also cautious.
