Grease crease is the crease in-between the thighs and buttocks/hips from a front vantage point generally visible while a female is seated. This majetic sighting is more prominent on thicker women.
The praxis of sliding your phalanges inside of the Grease Crease while shellacking your bae from the back will warrant a euphoric sensation.

Girl 2: What do you mean?
Girl 1: There's a huge crease in his dick from wearing those tight jeans.
Girl 2: Oh, my boy has one too, he got ran over by a snowboarder!
