Sherliam

Two gay men. A mentally ill detective (Sherlock Holmes), and a gay ass math professor who kills evil nobility (James Moriarty). The ship comes from a criminally underrated animanga series called "Moriarty the Patriot" (Japanese: 憂国のモリアーティ, Hepburn: Yuukoku no Moriarty). If you happen to see this manga in a Barnes and Noble, be sure to get your hands on it. If you read this manga, you're automatically hot and I love you.

Person: Hey I ship Sherliam and I ready Moriarty the Patriot.
Other person: OMG YOU'RE GAY AND HOT PLEASE MARRY ME
