Usada Pekora is a rabbit-themed virtual YouTuber from Hololive's Japanese branch, a member of its third generation who debuted in 2019 and became known for her mischievous humor and signature peko speech quirk. Clips of her voice travel widely because her exaggerated delivery turns even throwaway lines into memes. This particular line riffs on simp, the internet slang for openly adoring a person or fictional character, and fans use it as a self-aware badge of honor. It belongs to the same wave of short anime voice memes as Onii-chan, onii-chan and anime ahh, bite-size reactions built for edits and punchlines.
