This is not clutch "sticking," it's "slipping". The pressure plate/clutch springs don't have enough clamping force to either bring the engine speed down to the transmission speed, or make the tires spin and bring the transmission speed up to the engine speed. It usually only happens when the clutch is hot and you impart a bunch more heat into the disk, overheating it. If you keep on the throttle and keep slipping it after this has happened, you can "glaze" the clutch, where it will keep slipping until the gaze has been burnt off.

I did this to my Corvette somewhere between 10 and 20 times over the course of it's life and the stock clutch survived to 54,000 miles when I sold it. It does decrease the lifespan of the clutch, but doesn't neccesarily kill it right then and there.
