It's when you have sex with a girl, during her period. The point is your "hero/penis" will go into the cave, do what has to be done, and it will come out all bloody, like if you've killed a dragon.
It's a reference when the knight/hero is going into the cave with the sword to kill the dragon and comes out with a bloody sword.
