The Grease Effect 

This is an effect in movies and tv where there are two groups of people and by the end of the movie or show each person in one of the groups has paired up romantically with someone from the other group. For example how in the musical Grease each of the T birds by the end of the movie is dating one of the pink ladies.

This movie used the Grease Effect to pair up all of the characters.
The Grease Effect was used in White Christmas so that each of the guys could end up with one of the girls.

Interdimensional grease denomination 

The act of sticking your penis through a black hole (assuming you can withstand the black hole devouring you) and allowing whatever is on the other side to grease your mandingo, you then pull it out and smack a complete stranger in the face with the remnants, the person on the receiving end of the post interdimensional mandingo slap then has to wrap their fingers around the shaft of the mandingo (gently) and say "ooga booga" 3 times in 5 seconds. When the interdimensional grease denomination is done correctly the person pursuing it will nut 50 times.

Man 1: Hey man, have you tried Interdimensional grease denomination?
Man 2: Nah, you?
Man 1: Hell yeah man, never came so hard in my fucking life.

natural grease-fitting

Humorous term for a female's coochie, into which a male "injects" a special "lubricant" with his "grease gun".

The real reason dat many older ladies have so much problems with painful/creaky hip-joints is that they aren't "getting some" nearly so often as da younger chicks usually do --- all ladies' hip-joints need periodic "lubricating" from a guy's inserting his built-in "greasing tool" into the "natural grease-fitting" located between her legs.
