Back Mount
From FightWiki
Back mount or rear mount is a dominant ground grappling position where one combatant is behind the other in such a way that he or she is controlling the combatant in front. Typically, the combatant in the inferior position is lying face-down, while the other combatant is sitting or lying on top. This is a very dominant, if not the most dominant position, since the top combatant can attack with strikes without the bottom combatant being able to see or defend.
