The 'Arya Stab' meme, frequently paired with the hashtag #NotToday, originates from the pivotal climax of the Battle of Winterfell in Game of Thrones Season 8. The image captures the moment Arya Stark performs a surprise leap and a clever hand-to-hand dagger drop to defeat the Night King. This scene instantly became a cultural phenomenon, evolving into a metaphor for narrowly escaping disaster or overcoming massive obstacles at the last possible moment. It is commonly used to celebrate 'clutch' wins against deadlines, responsibilities, or any looming threat that seemed unstoppable until the final second.
