Sinking the sub

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.

when you go into a toilet and see a turd so big it wont flush-so you piss on it as hard as you can to break it up and flush it so the next guy in there wont think you left that huge brown trout in there
