I thought this was supposed to be a petting zoo...
We've gotten sick of people petting us today.
But we never got the chance to rub you, though.
Oh, you rubbed us, alright.
The wrong way, that is.
The term the guinea pig uses is "逆鱗" or "touching the inverted scale", to push someone's buttons so to say. This comes from an old legend that says dragons become angry if you touch said reversed scale.
