I know what it is, Ponky, I just never use it. Call me mean, but watching people have a conniption is one means of interrogating them to see how they react. The slang is "pushing their buttons". Doing it to friends is wrong, but doing it to anyone not a friend, especially trolls, is
very interesting to me.
People are their base selves when drunk/inebriated or angry. High emotions such as love or anger, distort a person's ability to reason. It's very difficult to make someone love another, but making them angry is relatively easy if they are stupid, ignorant or inebriated. Once they reach that state of mind, it's easier to manipulate them and/or extract information.
Now tell me what you remember most from your psychology class, Perry. I'm listening.
