Clutch Dirt Bikes

Is it wrong to break the clutch in the dirt bike?
For fun you close the clutch a lot in my crf 80 (Give a lot of gas with the clutch in the release and then quickly making the skate wheels) .. Is it bad to do that?
I would have thought they were built for this type of things – to some extent. Doing it in the soft dirt, mud or sand should not be a problem. Could be expensive if you often do in concrete or tarseal.
