So does anyone in here know how to throw a good rock

yes

that is alright!

l can skip a stone if that counts.

No but l know how to smoke one! ;)

First you have to make sure the rock has no bitterness or anger towards anyone. Maybe a counselling session and prayer will make the rock good. After that just take it in your hand and fire it.
