Yes, someone with OCD can know what an e-girl is. Obsessive-Compulsive Disorder (OCD) is a mental health condition that affects a person's thoughts and behaviors but does not limit their ability to gain knowledge or learn about various topics, including internet culture and trends.
An "e-girl" is a term used to describe a particular style and subculture that emerged in internet culture. E-girls are typically young women who have a specific online persona characterized by certain fashion choices, makeup, and a distinct aesthetic. They often have colored hair (like pink or blue), wear bold makeup (such as heavy eyeliner and heart-shaped blush), and dress in a mix of alternative and cute clothing styles.
E-girls are popular in various online platforms, including social media, video-sharing platforms, and gaming communities. They might be known for participating in internet trends, streaming themselves playing video games, creating content, or interacting with their online followers.
In summary, knowing about e-girls or any other internet culture or trend is not dependent on whether someone has OCD or not. People with OCD can have a wide range of interests and knowledge, just like anyone else.
