"touched a nerve"
What a weird use of an expression.
It's often used in a heated Internet debate. I know what it means. What I don't understand is what the purpose of someone saying that after they made someone else mad?
I mean, imagine if it was in real life. You disrespect or insult, say, the teacher in your class, and then after he got mad you say haha looks like I touched a nerve.
Classroom would be like, huh? Ya think?
What was the point? You made him mad, and then claim that you touch a nerve. Isn't it a captain obvious moment?
It's like as if a guy tells a joke and after everybody laughed hard, he while smirking full of confidence then proudly says HAHA LOOKS LIKE I TOLD A JOKE!
Well of course you did! But somehow it is used that way in the Internet. All the time.
