乙后
[yĭ hòu]
This may represent someone considering themself special, perhaps like a unique queen ('乙'(yǐ) resembling a 'queen', after a '甲'(jiǎ), king) where '皇後'(hóu)=queen/consort. Alternatively, it could simply mean the user wants an identity different or distant from ordinary, daily life identities, indicating individuality. Note '乙后' is unconventional wording hence its meaning could be flexible and depends a lot on individual intention.
