Grell

A liquid substance consisting of semen, blood, and feces usually produced by making stanky anal love to a woman on her period then waiting for the wrongness to drip out. If one is impatient a straw may be used.

She woke up the next morning with a filthy puddle of grell forming underneath her anus.
