The 'Sign Bunny' (also known as the ASCII Bunny) is a minimalist meme featuring a rabbit created from text characters holding up a speech bubble or a physical sign. While ASCII art has existed since the early days of the internet, this specific bunny became a viral sensation on Twitter around 2014. It is widely used for 'sign-holding' humor where users place various messages—ranging from political statements and social commentary to wholesome reminders like 'drink water'—inside the bunny's sign. Its simplicity and versatility allow it to adapt to any trend, making it a staple of social media communication and digital expression.
