Both replies true but not much of an explanation
It's called compression lock because it's the opposite of a burnout. Lookup howstuffworks.com and look for drivetrain/differential or gearbox and click around.
Rev matching is using the accel to match the engine speed to the geared road speed. Again if you read through howstuffworks on it should be easy to pickup.
To stop it either be easier on the clutch, shift down into lower revs, learn to rev match (search).
Good luck.
