Verb meaning 'to pile up', used for buying large quantities of CDs or goods. Often seen as 'CDを積む'.

Describes a fan who focuses their obsession on one particular idol or unit.
A fan who supports only one member. '推し' means one's favorite. '単推し' contrasts with '箱推し' (supporting the whole group).
私は単推しで、他のメンバーにはあまり興味がない。
I'm a solo stan; I'm not that interested in the other members.
Literally 'in charge of'. Used to declare one's favorite member, e.g., '〇〇担当です'.

Describes actions typical of an idol otaku, such as following idols, attending events, or engaging in wotagei.

Directly translating 'otaku obsessed with idols' as 'アイドルに取り憑かれたオタク' sounds unnatural. Use the established terms above.
While 'ファン' (fan) is neutral, 'オタク' implies a deeper, sometimes obsessive interest. In idol culture, self-identifying as 'オタク' is common and not necessarily negative.
