This page is very much in a state of building, but this will be a comprehensive listing of every fun sex or sex-related term I can find. It is beyond disgusting in most cases, so, it's probably a bad idea to read on. That having been said...

   Defecating in the vagina of your partner.
2. Angry Dragon
   
   The act of a blowjob recipient striking the back of the head of the blowjob provider immediately after ejaculation in such a manner as to cause ejaculate to be expelled from the "giver's" nose, causing them to have the appearance of an angry dragon.
3. Angry Pirate
   
   Ejaculating in your partner's eye, followed by kicking him or her in the shin... the resulting "argh" of pain coupled with the limp and closed eye causes an appearance not unlike a pirate. An angry one.

   Ejaculating on your partners face then inducing a nosebleed (typically with a punch to the face).
