The 'AF' (As Fuck) meme is a linguistic intensifier used to amplify adjectives and emphasize a specific state of being. Originating from African American Vernacular English (AAVE), the acronym became a cornerstone of internet slang on platforms like Twitter, Tumblr, and Instagram during the early 2010s. In the world of memes, it is typically applied as a bold, high-contrast text overlay on images to describe extreme relatability, such as being 'Tired AF,' 'Hungry AF,' or 'Done AF.' Because it functions as a versatile modifier rather than being tied to a single image, it remains one of the most flexible and enduring formats for modern reaction imagery and social media commentary.
