Let's say you have a favorite band member, your bias. Then one of the other members does something that makes you rethink who your bias is. Therefore "Bias wrecker"

In k-pop you have a bias (your favourite member of a band), but you may get a bias wrecker. A bias wrecker is one who makes you rethink who your bias is. Usually in some cases,
your bias is the one who you can relate to the most, and a your bias wrecker is who you find the most attractive.
This is mine when I became an army:
Me: yep. Kim Namjoon (RM) is definitely my bias. He's so smart and cute.
*incomes Jin*
Me: ooo;)
*sees the way he dresses*
Me: omg:(
*speeks english*
Me: ahhhh!
*laughs in the famous Kim Seokjin way*
Me: that's it. I'm dead. Kim Seokjin is now my bias wrecker:)

Don't get me wrong tho, I love all of BTS. RM is still my bias, and Jin is my bias wrecker:) if I could have 7 biases, well there we go. They're all my favourite:)

Say you have a favorite person in a group (bias), and then you see another member of the group that makes you turn your head away from your bias, place the two members as equals, switch position of liking, or start questioning who your bias is.
Insert Name Hey, who is your Monsta X bias? Mines is Kihyun.
Y/N It has to be Hyungwon.
Insert name Oh my God, look at these funny moments of Minhyuk. Wait who was your bias again? Sorry I was watching this and stopped listening.
Y/N Uh... I don't really know.

In that scenario, bias wrecker is Minhyuk.

Bias wreckers are one or more other members of the kpop group your bias is in. they storm in and destroy your bias list leaving it in shreds, until your left with them and them only. Bias wreckers make it impossible to stay loyal to your bias, that is, if you don't make your bias wrecker your bias or second bias.
Kpop fan 1: Who's your bias in stray kids?
Kpop fan 2: um Bangchan
Kpop fan 2: *think of bias wrecker Lee Know*
Kpop fan 2: and Lee know
Kpop fan 1: oh cool okay.
Kpop fan 2: *in their mind*: dangit. you did it again Lee Know.
