A term used to describe female masturbation, generally with a sex toy, like a dildo or a vibrator. It is the act of the female pushing the toy so deep into their vagina, it is almost like they are sinking a submarine.

This was great fun in high school. The rules were simple - you had to make the substitute teacher (the "sub") cry by the end of the class.
