To "run a g" on a girl is to gangbang her or to run a train on her.
My nig, we ran a G on that lil red bitch yesterday.

Get the run a g mug.
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.
