I did a little research and I've got it now.
"Slipping occurs when the driven disc fails to rotate at the same speed as the driving members when the clutch is fully engaged. This condition results whenever the clutch pressure plate fails to hold the disc tight against the face of the flywheel. If clutch slippage is severe, the engine speed will rise rapidly on acceleration, while the vehicle gradually increases in speed. Slight but continuous slippage may go unnoticed until the clutch facings are ruined by excessive temperature caused by friction."

Thanks a lot for clearing that up...i think i need a new clutch
im pushing 90,000 miles on my car and it doesn't seem to slip at all, but the engine revs don't match the actuall acceleration of the car. does anyone recommend a particular brand/model over another.
