Wow...
But at least you had the balls to ask, so I won't laugh too much... There are a lot of people that act like they know things, when they don't. Those people are much more annoying...
Anyways, a grease fitting is a fitting on a moveable part, like a control arm, steering linkage, ball joint, etc. Basically, there's a pocket of grease in those types of parts. In the past, you would have a fitting on those parts, so you could add new grease, through the life of a vehicle. Helps keep the joint lubricated, and working properly.
But nowadays, car companies are sealing up these fittings, and saying they're, "Sealed for Life", which generally means they'll last around 100,000 miles, and then you'll have to replace them.
