Yeah you guys are talking about acting out while angry or raging.
When you are angry at something - like a government or at a teacher who slighted you, you can easily focus that anger into making BIG changes. Take the teacher for example. One time a teacher told me that I could not pass the test unless I took out my notebook and took notes. She was a real --- about it. So finally, I took the notebook out and opened it and purposely put my pen on the paper and never touched it again.
Subsequently (because I was pissed my intelligence had been slighted) I got 100%.
In all honestly if she hadn't pissed me off, I probably wouldn't have paid much attention. Being angry at something can cause you to focus in order to spite the source.
Alternatively, I could have thrown the notebook at her face and gotten expelled, but that's not the same thing (though still due to anger). That's just acting out on my feelings. You see the comparison I'm drawing?
