Grease Injection

(Noun) The act of inserting the movie "Grease" into your own, or your partner's anus; normally done out of the need for spontaneous sexual adventure or sheer hate for the film. Often confused with, the more common, "The Sound of Music Injection".

Last night, I performed a Grease Injection on myself while baby-sitting my neighbor's 3-year old.

"Did you inject her with 'Grease' last night?"
