During waxing/grooming, especially in manscaping, a fluffy star is to leave the area around the anus hairy.

Often used to describe a "hairy bumhole".
"I went for a wax the other day. The wax technician waxed my butt cheeks, but I still have a fluffy star."

"I needed to get a wax for my costume. I kept the star fluffy, it hurts too much to wax there!"
