Butterflying

Butterflying is a glitch in Halo 2 and Halo 3. You need 2 people to do this. One person has to jump on someones head repeatedly while the other person keeps on pressing RB and B repeatedly. It "cancels" a reload and a beat down to a lock on sequence allowing you to fly. In Halo 2, you press B and X repeatedly with an Energy Sword, but otherwise it is the same.
