An argument or fight between two or more stupid people. Especially immaturely and in front of a group of people.
Those two dumbasses, Ben and Jared, both liked the same girl, so they formed a retard rivalry and began yelling at each other like fucking five-year olds.

The retard rivalry between the homosexual HSM fanboy and the emotard went over the edge and eventually the two began viciously attacking each other.
