A sexual act involving 5 individuals: 3 males and 2 females. The Last Train to Paris is when a male and female form a train of sexual intercourse, leading up to the remaining two males performing an Eiffel Tower. Hence "The Last Train to Paris".

An act which involves a train of guys separating the butt cheeks of a woman and taking a dump inside. Possibly having sex with it? That would turn it into a "Rusty Nail" or a "Dirty Piston", which ever name you choose. You would be a fool not to.

A mystical man, who is relentless in his pursuit to fingerbash as many chicks as he can. Certain females are constantly fighting over tickets to the G-Train. Once the G-train l is knuckle deep and motorboating the shit out of them, that’s what we call a “Dirty G-train”.
“Oh wow look at me, I’ve got big tits and a gashing vagina, all I want is a ticket to score myself a Dirty G-Train”

Since I wasn't a newborn, I always held my pee to put on my cloth diapers, training pants, or underpants, and relieved my potty training accidents of pee inside my cloth diapers, training pants, or underpants!
