It is when a girl flexes her asshole open and a guy blows weed smoke into her asshole. And clenches her asshole tight. While peeing in her vagina then fucking her until she orgasms then having the man's pee and the weed smoke blast out as she orgasms.

A sexual act, irrelevant of orientation, in which one partner, henceforth referred to as "The Conductor", performs intense anal sex with the other partner, "The Caboose", to completion.
Upon completion the Conductor removes their phallus from the Caboose's sphincter, which at this point should be sufficiently gaped enough for the arrival of the next train. The Conductor then turns around and sits their buttocks of the Caboose's rear, and proceeds to defacate into the Caboose's gaping "station".
The Caboose will then push the train back into the Conductor's own asshole, and the pair will go back and forth until a second climax is reached, at which point, the climaxing partner will shout "ALL ABOARD!"

"Judy and I got a bit freaky last night and took a trip down to the ol' Detroit train station."
"I was feeling a little empty until Bill and I went down to the Detrot train station last night, now we're both pretty full."

Flushing local and rarely express that goes from 34 St-Hudson Yards in Manhattan to Flushing-Main Street in Queens. Has a total of 22 stations and it has an express train that rarely goes express even though it says "This is a Manhattan or Queens bound 7 express train." Its just another local train. It goes express from Queensboro Plaza to Junction Blvd, then from there to Mets-Willets Point during rush hour on weekdays. The ride is a smooth experience sometimes stopping in the middle of nowhere but the train ride is fun.
"There is a Manhattan bound local 7 train to 34 St-Hudson Yards, approaching the station, please stand away from the platform edge."
