The act of farting into one's own hand, lighting the gases then "throwing" it into an unsuspecting target's face.

Or if some is lighting up you throw the ninja ball through the lighter flames igniting the gases.
Hand me that lighter, I have to fart and Im going to make a flaming ninja ball and through it at Joe.
