A euphemism for a gangbang or a gang-rape.Some here are afraid to admit that it refers to rape and say it is VOLUNTARY.It is safe to say it refers to either group sex or gang rape.This word is usually used by gangstas and thugs.

Watch the TRAINING DAY scene when alonzo stops the white kids in the gang neigbourhood.

when lots of boys in a white collar office try to hit my vajayjay in a series of poundings on the board room table. this usually follows a strategic meeting which inevitably started with 2 bottles of wine. i liked it and everyone should get a ticket to this train. i must admit that when they were discussing "running a train" i was blind to the real definition. but after experiencing a "train" bein run on me and my vajayjay, it was quite enjoyable especially the handcuffs and i recommend all office women give it a try. peace out and i holla'd back wit sum youngins'
we run a train on dis hoe once a fiscal quarter while discussing strategery
