A character is holding any sort of long polearm behind their back, rather than in front of them. The 'polearm' in question can be anything like a spear, staff, broom, rod, or such. This tag basically encompasses the variety of postures that characters can utilize to accomplish this.
Note that this tag refers to when a polearm is actually being held in the character's hands. If it's strapped to their back, planted in the ground behind them, or they're otherwise not holding it, don't use this tag.
