Plasma can often be called the fourth state of matter, after solid, liquid, and gas. It is also sometimes described as an ionized gas i.e. a gas when the degree of energy is really high how the electrons escape from the atoms. This leads to soups of charged particles that happen to be overall quasi-neutral. If it's not something you've experienced yourself, no doubt you've run into people who find themselves bitter about past experiences or missed opportunities and should not appear to stop talking about them. It's hardly nuclear physics to believe that they are not doing themselves worthwhile should they be constantly looking back.
