    • Bias whecker is when you already have a bias but bias whecker is when you love a guy or girl in a group more then your other bias if that makes sense 😊

      • It’s when you have a bias, but when there’s someone else who keeps threatening that place as your bias. Take BTS for example:

        My bias is Jungkook, but my bias wrecker is Jimin (AND V!) They both do things that make me want them to be my bias.

    • Bias wrecker is an idol who you are starting to like more than your previous bias. For example your bias is jungkook but you find baekhyun more sexy and attractive too. So baekhyun is your bias wrecker (also bias ruiner).

    • For example: Someone is your bias. Then you see someone that you also kinda like. So like, the bias wrecker tests your love for your bias and wrecks your bias list. i was too late replying to this huhuhu;;

    • A group that is made up of members from a band, but not all of them – only a sub-group. For example: Orange Caramel is a (sub) unit of After School, etc.

  3. Thank you so much I know others here but, I wanna know others so I LITERALLY know what the others say. What’s the different about Unnie and noona BTW??

  4. This might seem obvious but I wasn’t sure what was meant exactly by debut of an idol or idol group, in the context that there’s a larger picture. For instance I had no idea they are chosen by a company and trained ahead of time and then make a debut after years of training with a certain company. I mean, teenagers and young people aren’t groomed like that in the U.S.

    Also, now that BTS is so huge, might want to add their fans, Army/Armies, to the list, unless you’ve already done so. I didn’t check.
