Throwing it overhand is a masturbating grip where the thumb is closest to the base and the palm of the hand is on top. This grip was derived from a common way to throw dice.
I got so bored of the normal grip I decided it was time to start throwing it over hand, and i have never been back.

If masturbating grips were sex positions: The normal one to throwing it overhand is like missionary to doggy style.

Once you go overhand you never go back.
