an expression used to describe an experience that was ‘frightening’ to the speaker, but not really a huge deal to anyone else. While it isn’t disputed that some are “literally” shaking, most who use this phrase are simply being dramatic.
Ex. “The Target manager wouldn’t sell me the $30 electric toothbrush that was marked for $0.01, so I had to contact the police. I’m literally shaking right now after experiencing this.”
