death menstruation

When the odor of a woman's period blood is is so rancid, not even she can tolerate herself.

(female 1) Omg! Why does the bathroom smell like a rotting carcass?

(Female2) There's only one thing that can explain that smell. It's that time of the month for one unlucky bitch. But it's not just any period, it's the Death Menstruation!
