The term "fark" is a polite version of a similar 4-letter swear word! My location is near Chicago (see my location info). I am bi-lingual, so Spanish works for personal messages. The moderators of the the forums will censor any postings in other languages. Hopefully they will let me post this quote:
La palabra "fark" es una version gentil de una palabra gruesa de cuatro letras simular.
