Olderbrothercore (also called Older Brother in the 2000s or Early 2000s Older Brother Core) is an aesthetic revolving around stereotypical traits associated with teenage-aged older brothers in the early 2000s-early 2010s, typically ones considered popular, rebellious, and traditionally masculine. These archetypical older brothers often come from 2000s media, which created this character to be "cool" and often either a mentor or a bully to their younger sibling.
