K-Pop slang term
What does Bon-jin (본진) mean?
About this term
Bon-jin (본진) is your main group or idol when you follow more than one fandom — literally your "home base." Multistans use it to say which act they prioritize for albums, concerts, and streaming.
It pairs with choi-ae (favorite member) and cha-ae (second favorite). Knowing bon-jin helps you read Korean fan posts that rank loyalty without confusing it with a casual listen.
Frequently asked questions
Is bon-jin the same as bias?
Not exactly. Bias / choi-ae is usually a favorite member. Bon-jin is your main group (or main idol act) overall.
Can you have more than one bon-jin?
People joke about it, but the word implies one main camp. If you split equally, fans often say they are multistans without a clear bon-jin.
