The deep, dark depression one sinks into upon finishing the fifth Harry Potter book. The mood is characterized by a feeling of intense loss, loneliness, and hopelessness. Essentially, there is a deep black chasm somewhere near the heart.
Concerned Friend: What's wrong with Ted? Has he been crying?!
Wise Friend: He's fell into Sirius Blackness. I'll give him some chocolate.

Get the Sirius Blackness mug.
An amazingly sexy Marauder, who is also known as Padfoot. Even in death he is much sexier than you.
You disagree? Two words mate. Flying. Motorbike.

I would.
Sirius Black, the most perfect fictional male character ever created.
Get the Sirius Black mug.
Sexiest book character in the world. Ever. Sirius, aka Padfoot, and Snuffles, is Harry Potter godfather who got sent to Azkaban for a crime he did not commit. Before this, he was the hottest damn thing ever to walk the halls of Hogwarts School of Withcraft and Wizardry. He is not officially gay but according to a large portion of the Harry Potter fandom, he is Remus Lupin's bitch. Which is so not a problem. Sirius Black is the only fictional character that is sexy enough to fan-girl over.
Damn Remus, look at Sirius Black over there! He's not wearing a shirt.

Godfather of Harry James Potter, who is not dead, and will live on in the memories of his fan-girls (me) forever!

Attened Hogwarts for 7 years, was part of the infamous group of pranksters' known as the 'Marauders', Remus Lupin(Moony), Peter Pettigrew (wormtail), himself, and James Potter (Prongs). He was framed by Peter Pettigrew after the deaths of Lily and James Potter, and sent to Azkaban prision for 12 years before he escaped! Something one had ever done before.

Sirius is also an animagi, he transforms into a large, black, bear-like dog. Known as Padfoot, and/or Snuffles.

He was a fan-damn-tastic (straight) hottie.
Snape's worst memory: "With another shock of excitement, Harry saw Sirius give James the thumbs-up. Sirius was lounging in his chair at his ease, tilting it back on two legs. He was very good-looking; his dark hair fell into his eyes with a sort of casual elegance neither James's nor Harry's could ever have achieved, and a girl sitting behind him was eyeing him hopefully though he didn't seem to have noticed." (Harry was watching Sirius Black and James Potter durning they're O.W.L. exams)

Dumbledore: "Sirius was a brave, clever, and energetic man, and such men are not usually content to sit at home in hiding while they believe others to be in danger."

AKA: Padfoot or Snuffles

Harry Potter's presumed dead God-father/doggy. One time best friend of James Potter and Remus Lupin, "killed" at the hands of one evil bitch of a cousin Bellatrix Lestrange. Also, hands off, as he is betrothed to the aforementioned Remus Lupin.
"Hello, I'm Sirius Black, the sexiest thing to come out of Hogwarts since...er...ever!"
