The 'Y'know, Nyah' meme is a popular internet trope used to represent the stereotypical 'cat-girl' aesthetic common in anime culture. It usually features a character performing a cute pose with cat ears while making the 'nyah' sound, a Japanese onomatopoeia for a cat's meow. This specific phrase gained traction as a reaction image used to convey playful mischief, forced cuteness, or ironic 'cringe' humor depending on the context. It has evolved through various redraws of popular characters across fanbases, making it a versatile tool for mocking anime tropes or simply expressing a feline mood in online discussions.
