The acronym 'TL;DR' (Too Long; Didn't Read) is a foundational element of internet slang, dating back to the early 2000s on forums like Something Awful and Usenet. It serves two main purposes: providing a concise summary of a lengthy post or dismissively signaling that a piece of text was too verbose to bother reading. In meme culture, the TLDR template is frequently used to highlight the absurdity of over-explanation or to simplify complex topics into humorous, one-sentence punchlines. It perfectly captures the fast-paced, low-attention-span nature of digital communication, making it a favorite for social media comments and sarcastic corporate replies.
