4Minute seonsaengnim are back!
Now they're here to teach you:
Start listening at 1:28
They are using this to mean "Hate" but usually it is used this way:
싫다 - to not like
싫어 - I don't want to! or I don't like this!
Basically when your friends say "stop listening to kpop" or "turn off that kdrama" just yell "싫어!" (sshi-reo!)
