noun
polyamory (without favoritism)
Refers to a relationship style, often associated with women, where one loves multiple partners equally without showing favoritism. A modern, somewhat niche term.
彼女は分散恋愛を実践していて、複数のパートナーと平等に付き合っている。
She practices polyamory without favoritism, dating multiple partners equally.
A broader loanword for polyamory, while 分散恋愛 specifically emphasizes equal love without a primary partner.
Compound of 分散 (dispersion, distribution) and 恋愛 (romantic love), literally 'distributed love'. The exact origin is uncertain, but it appears to be a modern coinage describing a non-hierarchical polyamorous approach.
