Ouch! I'd have to agree with Cat'sHouse and change the way you hold him.
Maybe, for a while till the habit is broken) hold him where you have a hold of his back feet, or even just one.
I don't think you're going to be faster then his "launch" in order to drop him, like was suggested. There are rarely preliminary signals given before they do and your reaction to his movement is just going to be milliseconds too slow and his launch will be successful.
Just hold him in a new way for a while, see what happens.
