MLG Reload
In Halo 3 (or another Halo), once you have switched to bumper jumper, like a true MLG and have played on default for such a long time, when a person has a mauler or shotgun and you shoot and then beat down to get a kill, one would just shoot and MLG reload in their face because the buttons have been swapped.
"Fucking MLG Reload, I totally had that piece of garbage and now I can't get his nuts out of my mouth!"
