Ususally someone that plays First person shooter video games that is really horrible and cheats. Plazmas like to blame everyone around them for there own mistakes. Plazmas are highly known for there screaming and raging in teamspeaks, ventrilo.. ect.. they for some reason happen to have the same first name Max. Be sure if a plazma connects to a video game that you gobally mute him or you will suffer the servere raging and cheating your best bet is to stay away at all possible costs.
