Where a guy pulls out of a woman after sex, only to be surprised to find his cock covered in menstrual blood because she didn't tell him she was on her period.
Guy 1: So did you score with Suzie last night?
Guy 2: I gave her a proper smashing, but the dirty bitch didn't tell she was on her rags - gave me with a blutwurst surprise
Guy 1: Jesus man... that's just nasty
When you are engaging in anal sex while your partner has to take a shit, and it gets shoved deeper into their rectum until it will no longer remain inside them, and it splashes out.
"Bro, what the hell was that? We were engaging in some hot anal sex! What's with all the shit?"
"Sorry bro. Didn't mean to give you a Peanut Butter Bratwurst."
An exceptionally massive and nutty turd. This type of jobbie has been known to crack lavatory bowls and is a subspecies of the Guatemalan depth charge.
Oh man I just let a nutty bratwurst go. If you hear a noise in the night it'll be my sphincter snapping back into place.
Norwegian Bratwurst is a term used in response to the presentation of any other term that one may be unfamiliar with. It may be used as an escape mechanism from a situation/question that tests one's knowledge of Urban Dictionary terms, or just a joke on a friend to test their honesty in being presented with an Urban Dictionary term.
An example of both applications is as follows:
Michael: Hey, Eloise, have you heard of a cream pie?
Eloise (with discomfiture): No, I have not. But have you heard of a Norwegian Bratwurst?
Michael (with false confidence): Yeah, that's disgusting!
Eloise: Moron! Norwegian bratwurst does not exist. I simply made it up in order to play you the fool.
