When your using an inaccurate fully automatic weapon in a first-person shooter, such as Halo, and to make it more accurate you jiggle the trigger to burst fire.
Guy 1: "Man, I keep missing with this shitty assult rifle!"
Guy 2: "Dude, try trigger jiggling."
Guy 1: "Holy shit! This works way better!"
