An incredibly bad(smelling)idea that leaks out of someones head, although these bad ideas can be easily avoided through basic common sense, The term "brain fart" is mostly associated with unavoidable bad ideas that originate from a boss or employer.
Bob's boss looking rather proud leaks out a rather large and foul smelling brain fart by telling Bob "you will have two week work deadlines at the beginning, middle and end of each month".
Bob can easily identify this as a brain fart from the really bad smell and since 2 weeks of time would not exist inbetween the end of one month and the beginning of another.

When someone sits on your ear while you are sleeping and farts. Usually done as sick pranks at late night parties.

A total lack of recognition.
A silly mistake.
Can be stress related.

An entirely new stage of confusion. It's like having a "brain fart" except for a breif moment you can not remember anything. Your brain feels like it has shut down becuase one thing is so difficult to understand. It leaves you in a whole new state of confusion and befuddlement.
The problem was so hard it left the kids brain farted.
