The 'I Know What You Are' meme features a close-up image of a white dachshund named Whitney Chewston, who gained internet fame for her seemingly judgmental and side-eye expressions. Often referred to as the 'homophobic dog' due to ironic captions first popularized on Twitter in 2022, the meme is used as a playful way to 'accuse' someone of belonging to a specific community, fandom, or character archetype. The humor stems from the dog’s squinted eyes and suspicious glare, making it the perfect reaction image for whenever someone is acting 'suspiciously' like a gamer, a fan of a specific show, or simply being themselves. It has since evolved into a versatile template for calling out any behavior with a mock-serious tone.
