重度腐女

'Heavy Otaku Girl'. Refers to someone heavily into otaku culture. An otaku is an enthusiast or collector whose interest in popular culture goes deeper than the average person. A 'fujoshi' is a sub-group interested especially in manga and anime featuring homosexual relationships. So here it refers to girls who immerse themselves deeply in the fan culture involving romantic stories of same-sex relationships typically between male characters, which is also part of broader fandoms.
