The 'Homophobic Ruby' meme features Ruby Hoshino from the popular anime and manga series Oshi no Ko, typically depicted with a look of intense disgust or judgmental suspicion. Despite its provocative name, the meme follows the tradition of 'Homophobic Dog' (Whitney Chewston), where a character is humorously portrayed as being aware of—and judgmental toward—specific behaviors or 'vibes.' It gained traction within anime communities on platforms like Twitter and Reddit, often used as a reaction image to 'cringe' posts or shipping discourse. The template is a staple for fans looking to express a witty sense of disapproval using Ruby's expressive facial features.
