In the context of yaoi and boys love, "seme" and "uke" are terms used to describe the roles of the characters in a romantic or sexual relationship. The seme is typically the more dominant or assertive partner who takes the "man" role and leads in sex, while the uke is the more submissive or passive partner who takes the "woman" role and is led in sex. The terms are also sometimes used more broadly to describe behavioral or personality traits, with the seme being more aggressive and the uke being more receptive. Its worth noting that these terms are specific to the yaoi and boys love genres and are not necessarily applicable to all same-sex relationships.
