Meaning

"Duo dan" (multi-stan). Fan slang for liking multiple idols. Can also mean liking multiple contestants in the same audition show. Example: (Idol Producer 1) I like both cxk and cln. This situation is "duo dan". Opposite is "wei fen" (solo stan). Some solo stans oppose multi-stanning, but it's OK to like both as long as you're sincere to each.
