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.

My girlfriend was grease dried after we had sex yesterday morning.
I made her do a grease dry for me to suit my fetish.
