An angel from the hit show Supernatural on CW TV. He is mostly seen with Sam and Dean, the two main characters in the show. You can tell who he is by his tan trench coat and blue tie.

His name is almost always spelled "Cas" by the fandom and "Cass" by the writers.

Mostly, he is shipped with Dean to form the ship Destiel (which should totally be canon , by the way.) Sometimes, he is also shipped with Meg, a demon, or Sam, Dean's brother.
Fan 1: Awwww, Castiel is such a cutie. He needs to be protected at all costs.

Fan 2: Trueee. Dean will protect him though.

Fan 1: Well, Cas was the one who raised him from perdition, so you could argue that Cas should protect Dean. (*cough cough* from other women because destiel need to be canon obviously)
Fan 2: Ohohohohoho, was that subtext

An angel from the CW hit show "Supernatural".

Aside from gripping people's souls tight and raising them from perdition, Castiel's hobbies include drinking liquor stores, having copious amounts of eyesex with Dean Winchester, and telling jokes that are funnier in Enochian.
When embarrassed or confused, Cas will lower his gaze and shift uncomfortably before fixing you with a puppy dog gaze that has been known to render both women and men completely helpless.
"It literally means 'You breed with the mouth of a goat. *pause* It's funnier in Enochian"

"I do not understand that reference."

"Hey, ass-butt."

Dean: (On Castiel trying to find God) "Try New Mexico, I hear he's on a tortilla."
Castiel: "No, he's not on any flatbread."

Sassy gay angel from the television show Supernatural.

Hobbies include drinking liquor stores, gripping peoples souls tight and raising them from perdition, and having large amounts of eyesex with a one Dean Winchester.

His greatest weapon is the ability to render both men and women completley helpless with one glance of his puppy-dog eyes, which are often seen when he is embarassed or confused.
