what is a bias?

In stray kids. I just can’t live… first my bias was Felix…then I got bias wrecked by Minho but like I still don’t wanna give up Felix so then it’s just I have two biases. Now I got bias wrecked by Hyunjin but I still don’t wanna give up felix or minho. So my stray kids biases are the dance line i guess. but like at this rate imma get bias wrecked one by one and then i’m just going to end up biasing everyone because I won’t give up current biases. smh why am I like this?
