Vehicle flinging is a movement technique. It is performed by slightly turning the Warthog from left to right and exiting. If you time it properly, the rear-left tire of the Warthog should hit you, launching you into the air. It is used on Halo (Halo CE), where you can fling into the Forerunner complex much faster than walking into the tunnels.
You can also fling using a Ghost. Since Master Chief exits the Ghost on the right side in Halo CE, you have to turn from right to left.
Backpack reloading is a combat technique. By pressing Reload-Reload-Switch Weapon (XXY on console), you can have your secondary weapon out while your primary weapon reloads itself. You should hear the reloading noise while your secondary weapon is equipped.
To double-melee in Halo CE, press Melee-Grenade-Melee (BLB on console). You will be able to cancel the melee animation by throwing a grenade and melee again.
