I was recently on a flight where I was able to listen to the Pilots
speak to Air Traffic control. It was quite fascinating but I
understood very little of what they were saying. Does anyone know of
a good resource for their terminology? Also, I was wondering if anyone
knew what the following mean, I heard them used a lot.

Heavy
Bugsy

Not sure what "bugsy" means but it could be an airway intersection.
Intersections are 5 character names which identify a given spot
in the airspace, usually an intersection of VOR radials but can
be other things like an outer marker, etc. etc,

"Heavy" means the aircraft is a large aircraft, like a 747 or
somthing similar. Other than the AIM (Aeronautical Information
Manual) I'm not sure of any other sources for the various terminology
and buzz-words you are looking for. A lot of it has developed
over time and is well understood by experienced pilots.
