The Suzy Lu meme centers around the Scottish YouTuber Suzy Lu, who became a focal point of internet culture following a series of copyright controversies in late 2019 and 2020. After she allegedly issued copyright strikes against several fellow creators for criticizing her content, the internet responded with a wave of memes featuring her expressive reaction faces. These templates are typically used to parody DMCA abuse, excessive emotional reactions, or the 'drama' side of the YouTube anime community. While originally rooted in controversy, the meme has evolved into a general-purpose reaction image for situations involving strict rules or unexpected consequences.
