Brother Zim ... I call your attention to a few items of interest, here:
FIRST - The sexual definition in the Urban Dictionary is "run train," as well as, "run a train."
SECOND - Under "run train" in the Urban Dictionary, the Top Definition and the next four definitions provided all have to do with a girl having group sex with a bunch of men. And, the reference is to a willing "gangbang," not "gang-rape."
THIRD - The sixth definition under "run train" in the Urban Dictionary is the one that lamely refers to pushing legislation through with the opposing party unable to prevent it. GUESS WHEN this particular definition to the Urban Dictionary was entered, eh??? It was conveniently entered on January 22, 2019. You want to know when The Bronx Valley Girl made her "run train" comment? It was on January 16, 2019. So, either The Bronx Valley Girl ... or more likely one of her supporters ... quickly made this entry to help cover for her ridiculously imbecilic mouth.
So, in truth, there is ONLY ONE real definition. I know it. You know it. Everyone else knows it, too - including The Bronx Valley Girl.
