Coat Cape

Sometimes, to show how cool a character is (or just how broad his shoulders are), all he has to do is wear his coat like a cape, as in not bothering to use the sleeves. This is often a trait of Japanese Delinquents.

Don't expect them to either slip or fall off, even against powerful wind, explosions and the character running and jumping all the way, unless it's for dramatic reasons.

Compare Coat Over the Shoulder. Not to be confused with Badass Longcoat, which often resembles a cape but is worn normally.

Examples of Coat Cape include:

Anime and Manga

Most of the high-ranking Marines in One Piece wear their coats like a cape. Word of God says that they're kept in place by justice.
Yami has done this from time to time in Yu-Gi-Oh!.
Common in Hellsing. Integra in particular is rarely seen otherwise.
Taki from Hyakujitsu no Bara does this on at least one occasion with his Badass Longcoat, with Dramatic Wind for added effect.
Colonel Roy Mustang in Fullmetal Alchemist often does this before going into full-bore flesh-roasting Badass mode.
- Scar does this too on occasion. (If I'm not mistaken.)
Kazuo Kiriyama does this in the Battle Royale manga; His gakuran's top is inexplicably long compared to his slacks, and stays on his shoulders even when he's subjected to explosions or jumps off a cliff. And although it starts out as a regular school jacket, by mid-manga it starts doing things like this, and then near the end it's basically a separate living entity that perches on his shoulders.
Mifune the bodyguard from Soul Eater wore a coat like this both in his first and last battle against Black*Star.
Hibari Kyoya from Katekyo Hitman Reborn pulls this off all while whacking enemies with tonfas sometimes attached with whips. He still manages to keep his coat on at the end of the battle. Perhaps he actually pinned his coat onto his shirt? Either way, it gives more leeway to make his entrances more awesome with his sleeves flying about flashing his disciplinary committee badge, which he is the president of.
Germany and Greece of Axis Powers Hetalia occasionally sport this look. As does Molossia.
Seiichi Yukimura from The Prince of Tennis.
Black Jack is one of the older manga examples, his flapping coat being a big part of his signature look.
Howl in Howl's Moving Castle starts out wearing his jacket this way. He stops wearing the cape when Character Development hits.

Film

Kazuma Kiryu in the Yakuza live action adaptation wears his jacket like this near the end. The reason is pretty much so that it can be blown off by a helicopter so he will be shirtless for the dramatic final fight scene.

Literature

In Hornet's Sting by Derek Robinson, one of the pilots wears his coat like this while pretending to be a Portuguese lord whose checkbook he found. Needless to say, played for comedy, rather than badassery.

Live-Action TV

On The Monkees, Micky did it when he was pretending to be a big-time movie producer, along with using a cigarette holder.

Tabletop Games

Commissars in Warhammer 40,000 are often depicted wearing their jackets like this.

Video Games

Persona 4: Kanji, as pictured.
Mao from Disgaea 3: Absence of Justice
Ujiyasu Hojo from Samurai Warriors 3
Tyrell Badd in Ace Attorney Investigations: Miles Edgeworth.
- And Ichiyanagi Yumihiko from Investigations 2.

Web Comics

Bethany from Afterlife Blues always wears her Badass Longcoat this way; she often holds it in place when she isn't using her hands for something else.

Real Life

In World War II, Reichsmarschall Hermann Goering was often photographed wearing his coat this way.
In early 20th century it was customary for gentlemen to wear an overcoat outside regardless of the temperatures. Especially in Southern Europe it became customary to wear them in this manner to avoid excessive discomfort during the summer months.
