friendenburg 

It is when the relationship of one or more of your friend(s) goes sour really fast.

My friendship with Joe is going through a major friendenburg right now.

Freudenburg 

A person who loves to fornicate with small animals. Specifically puppies and kittens. Sometimes wild animals will do.

Look at that guy screwing your dog, what a Freudenburg!
