Seems pretty straightforward to me...
Vulch-When someone shoots me on the runway or having just lifted.
bounce-When I shoot someone on the runway or having just lifted.
bnz-When I dive in from above and shoot someone down who's engaged with another friendly.
Pick-When someone dives in from above and shoots me down when I'm engaged with another enemy.
Cherry-Sort of an amalgamation of a vulch and a pick.
timid-When people run away from my slower plane. When I run away from other peoples' slower planes, it is flying smart.
gang-What happens when I dive into a crowd of bandits and get under them.
horde-A large group of enemy planes. A large group of friendly planes is called a 'mission'.
HO-A shot taken from in front of the 3 o'clock-9 o'clock angle on the aircraft where I get shot down.
front quarter-A shot taken from in front of the 3 o'clock-9 o'clock angle on the aircraft where I shoot down the enemy.
haxxor-A person who did something I don't understand in their aircraft.
hypocrite-...Nah. Someone'll take it personal no matter what I say.

Vulch = Shooting down a plane either taking off or landing
Bounce = Attacking an unsuspecting bandit
BnZ = Boom and Zoom, one of many Energy fighting tactics
Pick = Short for "Cherry Pick" and it's attacking a bandit that is engaged in a fight with someone else
Cherry = See "Pick"
Timid = Players that don't like to fight
Gang = Being attacked by a large group of bandits
Horde = A large group
HO = Head on shot...when both planes both have a firing solution on each other. If one plane does not have a firing solution, it is not a "head on".
Front Quarter = Engaging a bandit from the front 3-9 position, a Lead Turn is an example of such maneuver leading to a front quarter shot
Those have been the definitions for those terms since the days of Air Warrior.
ack-ack
