DD dii dii
Loves every member equally.
What does dii dii mean?
Short for 誰でも大好き, "I love them all". A DD cheers for the whole lineup instead of picking one. Some say it warmly, some with a raised eyebrow.
Example
あの人はDDだから、メンバー全員のうちわを持ってる。
He's a DD, so he owns a paper fan for every member.
Vibe
Who you can say this to, and how it lands.
Friends only Casual. Natural with friends, out of place at work or with strangers.
Culture note
In idol fandom, choosing one favorite is almost a statement of loyalty, so DD lands somewhere between generous and non-committal depending on who is saying it.
The story behind dii dii
Japanese fandom loves an alphabet shortcut, and DD is one of the oldest still standing: 誰でも大好き, I love them all. It comes out of idol fan culture in the 2000s, a world where the vocabulary for how you love was every bit as developed as the vocabulary for whom.
What keeps it from being neutral is economics. In a system where votes, event tickets and randomised merch all reward concentration, spreading your affection thinly reads as generosity or as a failure to commit, depending entirely on who is speaking. Plenty of fans wear DD proudly. Plenty of 単推し say it the way you might describe a person with a great many hobbies.
