Sumo Prarie Dog
When two individuals rear up to one another standing anus to anus and begin to simultaneously excrete fecal matter with the goal of overpowering their oppent's specemine back into the cavity from which it was origially lodged.
I bet my friend she did not have the fecal fortitude to overpower my log of dense consistancy and when put to the test of a round of Sumo Prarie Dog, I easily banished her weak stool back into her lower digestive region.
