I have punched down on the lock bar on more than one occasion. My go to word of choice when I lose it is, "Whore!" I don't know why I call my machines whores, but I do. I also slammed a Back to the Future machine through a wall. If I recall correctly, I screamed out the word whore very loudly that time. I stopped doing that when I got married and had children. They don't need to hear it. I will do it in my head though. The machines don't need to hear it either. They know what I am thinking.
