A fold found where the booty and upper thigh join together.
Typically found on Pornstars, Dancers, Models, Gymnasts etc.
Easiest to see when women are doing the splits, squats or the usual Insta-Thot poses

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.
