Literally "To Long; won't read".
Moron 1: I'll be back in a few minutes; I have to get a shower. I also have to prepare something for me to consume. Since I just woke up. Its fun getting 12 hours of sleep. I went to bed around 9:30. Didn't really fall asleep until 12am
Smart 1: tl;wr
Moron 1: STFU
Short version of "too long, won't read".
This term is used if one thinks that another person is about to write some long text and therefore only used in Instant Messengers or Chats.
Kinda similar to tl;dr
Person 1: Hey, I gotta tell you something. Wait a minute.
Person 2: tl;wr.
A less abrasive version of TL;DR. It stands for "too long; will read" It means you have the intention to read a long passage, but don't currently have the time.
What you wrote is very interesting! TL;WR later.
Too Long; Wanna Read (less frequently used contrary variation of tl;dr).
(in response to an online post)
tl;wr -- anyone have a summary?
