Running a "G" is when you and your boy(s). find a slut willing to let you both hit it at the same time. Now to make it a "G" you have to hit it from behind while shes giving dome to your boy, then high five like you know your the shit, cuz u just G'ed that bitch out.
Chris and kenny were totally running a g on isabella at Dans party this weekend. Omg i bet she fuckin loved it.
