Used by people who listen to other people who have no idea what they are talking about. At some point I assume somewhere between Generation X and Y someone overheard a word being used and misinterpred it. Now legions of people born after 1977 are saying the word Feen. The word used which they misheard is Fiend defined as a person who is craving something in a maniacle way.
improper use of said non-word:

I'm feening some weed!

propper use:

I'm fiending some weed!
