Mongolian Nut Combuster 

A sexual encounter involving 3 males. One fully naked man is standing with his scrotum dangling and his legs spread wide. The two others are wearing full Mongolian native tribal gear standing 10 yards away from the man. One is facing his front, and the other is facing his behind. They begin chanting, and when the chanting reaches a climax, they both charge head first and torpedo dive into male 1's nutsack causing a full explosion, Then males 2 and 3 use the blood and mutilated testicles to masturbate.

I cant believe i just gave my grandfather a Mongolian Nut Combuster!

Codburger

Inspiration: A meat cutting industry was packaging ground beef when a customer had called asking the price of Cod Fish. After looking up the price of the Cod Fish, the wrapper had continued to package the ground beef without changing the name of the price tags. Thus labelling all ground beef as "Cod Filets"; which sparked the term "Codburger".

Definition: Untrimmed and unwashed vagina -- used so much to a point where nobody would wish to touch it.

She seemed to be a MILF until I saw her Codburger.
