攻攻攻万年攻受受受千年受
[gōng gōng gōng wàn nián gōng shòu shòu shòu qiān nián shòu]
A term often used in BL (Boys’ Love) fandoms, which implies an unchanging dominance and submission role-play dynamic between two males, where one remains dominant ('攻' attack/perpetrator) and the other submissive ('受' receive/victim). The terms are borrowed from fan works.
