BIF 

Brilliant Idea Fairy; the imbecile who doesn't help a situation and can actually make things worse. He or she will suggest ideas that are impractical, implausable or impossible. Most often found where senior management hasn't a clue and no experience and is directing operations.

BIF is very similar to the owner of a MBA with no practical work experience in the job you are performing who is attempting to make your job more productive.
