no bun hotdog 

When two men hold their erect penises parallel to each other on a horizontal plane and a third man places his erect penis in between them from the opposite direction, thus resembling a hotdog with hotdogs for buns.

Dude 1, “Dudes, hold out your dicks parallel to one another so I can put my dick in between them, thus achieving a no bun hotdog.”

Dudes 2 & 3, “OK.”

Cinnamon bun 

Effectively the same thing as a cinnamon roll. (A character or person who is adorable/innocent/precious/cute and must be protected at all costs, but may or may not be exposed to constant pain that they do not deserve).

The only difference in usage is that cinnamon roll is less common and does not generally imply that the character/person is in constant danger.

Person 1: "How did his ex do that to him???"
Person 2: "IKR, how could you hurt a cinnamon bun like that?"

Or

Person 1: "have you seen the new kid?"
Person 2: "yeah, he's such a cinnamon bun."
