From Wikipedia, the free encyclopedia

TL;DR or tl;dr, short for "too long; didn't read", is internet slang saying that text being referred to has been ignored because of its length.[1] It is also used to introduce a summary of an online post or news article.[1]

The phrase dates back to at least 2002,[2][3] and was added to the Oxford Dictionaries Online in 2013.[1]
