The successor to the spitball, not as gross but infinitely more painful. A hornet is a folded piece of paper, bullet-like in appearance, which is shot from an elastic band stretched between the thumb and index finger, at bare skin and unsuspecting heads. Very useful for sending notes with the added bonus of annoying the hell out of the receiver. Usually favored and obsessed over by militaristic kids who love practicing their head-shots/nut-shots on quiet kids or SPEDs. They can also be recycled for use as spitballs.
"What the hell was that?"
"Giant fly. Now could you pass me that hornet on the ground beside you there?"
In Halo 3, a UNSC aerial vehicle, also known as the AV-Attack VTOL. It can fly in any direction or hover, and it is equipped with two machine guns and two tracking missile launchers. Two passengers can sit on the side and offer additional fire or simply be transported. It is not as fast as the Covenant equivalent, the Banshee, but it is more maneuverable, more durable, and deadlier. A Plasma Pistol overcharged shot will cause the Hornet to fall to the ground.
