Someone who grew up never having a brother/sister, or he/she passed away/treated them horribly and they always tried to replace someone as their brother/sister, to fill in that gap of being an only child or someone without a brother/sister.
random person: omg they have brother issues/sister issues

me: yes they’re either an only child or someone without a brother/sister. 🙁
