The 'Why is my sister's name Rose?' meme is a popular four-panel comic strip format that plays on parental naming conventions. It typically features a son asking his father about his sister's floral name, to which the father explains that the mother simply loves roses. The humor arises in the final panel when the father addresses the son by a name representing his own personal, often absurd, obsession—ranging from 'Gacha Games' to 'Industrial Techno.' This format became a staple on Reddit and social media for its versatility in mocking niche hobbies and intense fandoms.
