What does the “What I Know About...” meme mean?
The humor lies in the gap between the author's absolute confidence and their complete lack of knowledge about the subject. It mocks urban legends or common misunderstandings within online communities. This format is used to illustrate total ignorance while pretending to be an expert, highlighting the absurdity of information circulating on social media.
Where does the “What I Know About...” meme come from?
The "What I Know About..." meme originated on Tumblr in 2012. The first known presentation was published on October 28, 2012, by user jacknoir-sexual. It aimed to explain *Homestuck* from the perspective of a sister who had never read the webcomic. Titles often followed the structure "What I know about X from my dash," with *dash* referring to the dashboard feed. The aesthetic mimicked Microsoft PowerPoint using Comic Sans font, poor quality copy-pastes, and random narration. On November 11, 2012, JinnyMoose posted "What I Know About Tumblr," which quickly surpassed 35,000 notes, popularizing the format that critiques vague rumors heard on the social network.
