A term used in Halo to describe someone who can drive the M-12 Warthog or Halo PC's M-12A1 RocketHog with apparent ease, pulling off tricks and killing people like there's nothing to it. You can achieve Warthog Ninja-ness by

1. Dodging multiple tank shots
2. getting a "Killtacular" kill while driving with no gunner
3. sneaking up behind people and running them over

You can also be a Ghost Ninja, or a Scorpion or Tank Ninja. Sadly, Banshee Ninjas do not exist because of the amazing lameness of the vehicle. Most Banshee pilots are simply referred to as Banshee Whores, and are disliked by most Halo PC players.
