look up any word, like bae:
An expletive that can be used much the same as "crap," but is less mainstream. It has the potential to sound like German, prompting many to ask for a repeat and to inquire as to the meaning and root of the word.

Krapf is derived from the American bus company KRAPF Buses. The company's motto is "The only way to go". It is true: The only way to go IS to take a krapf.
Krapf! The toast ALWAYS falls butter-side-down.
