Space Invaders

Space Invaders:

People who don't respect the personal space of other human beings.
Space Invaders most often invade the space of those who are smaller than they are for any reason, such as shorter height, thinner build, or smaller due to youth. They are also seen invading the space of those they have assessed (correctly or incorrectly) to be physically weaker than themselves, emotionally less "tough", or who are in some way disabled, injured, ill, elderly, or in a weakened condition.
