The Koala Copypasta is a legendary internet rant that hilariously deconstructs why koalas are allegedly 'horrible' animals, focusing on their low-energy diet, smooth brains, and perceived lack of survival instincts. First gaining traction on Reddit, the text is often used as a bait-and-switch or a detailed response to anyone calling koalas cute. The meme usually features a photo of a confused or screaming koala, perfectly capturing the chaotic energy of the wall of text. It has since evolved into a classic example of internet 'hate-posting' where the humor lies in the unnecessary level of biological detail used to roast a seemingly harmless marsupial.
