intergalactic redneckism
Casting aside all preconceived prejudices for fellow human beings to come together as a race to ban against intergalactic species. In the absence of said species, all prejudices conveniently return to the human race.
Two people are arguing at a stop light about the others road rage. An intergalactic space craft lands in the middle of the road. Suddenly, the humans ban against the outside specie and put all differences aside. These people are said to be intergalactic rednecks, or suffer from intergalactic redneckism.
