A sex move when the two partners connect bum cheeks and then proceed to defecate into each others anus; if only one person defecates then it is called the Subway train, although if both partners decide to poo, then it is the Subway train collision.
Man 1: So how was the girl last night?
Man 2: Oh god no, she has a scat fetish; she wanted to subway train me!
