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.
