The act of having intercourse with a woman during her period, wherein the man (or the person with the dildo) penetrates her vaginally, creating the "rust," and then penetrates her anally, sinking it in a deep dark place.

My cousin had her period, so I totally rusty submarined her.

When a girl pulls her pants down (her cheeks loomin' over yo' erect dick), pops a squat, and straight up takes a massive, gravy shit on the tip of your penis. Like, not even in a sexual way. She just has to poop.

Ted: "You remember that machine Wonka drove down the chocolate river?"
