when two guys are each doing a chick from behind, but they are in the same room and the girls are facing each other and the girls' heads are banging against each other. and whoever knocks out the other girl first wins.
watch two goats battling on youtube, substitute goats with women who are being fucked from behind, thus the battle goat.
