Spectre jumping
From Halopedia, the Halo wiki
More commonly known as the "Spectre Hump Jump" is a type of super jump, or super bounce, in which a person will drive a Spectre on top of a Wraith, get on top of the Spectre's cannon, and continuously crouching, and it will rocket them into the air.
How to do it
This trick works the best on a flat surface, such as Headlong. You will need a Wraith and Spectre. Position the Wraith on the flat surface. Get in the Spectre and drive it up the cockpit side (front) of the wraith, so that it is almost paralell with the ground. Get out and walk on top of the Spectre's cannon (DO NOT get in it), and crouch and un crouch (basically teabagging) the cannon for approximately 30 seconds. After the 30 seconds, jump and you should fly into the air. If you do this to long, you'll die. If you don't do it long enough, you won't go very far.
