A character from the anime/manga Black Butler. (Kuroshitsuji in Japanese.) Grell Sutcliff is a Grim Reaper who is in love with the color red and turned out to be Jack the Ripper. He is also very gay, (a transvestite, really.) and appears to have a thing for men in suits. (Sebastian, William, the Undertaker, etc.) He also wields a chainsaw as a Death Scythe.
Sebastian's day was completely normal until Grell decided to creepily stalk and take pictures of him.

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.
