Avatar® Course jargon. It is taking something out of existence. Discreate means to cease the creation of a creation. It is a halt to an existing flow of energy towards a creation (a thought, belief, or feeling).
The jargon "discreate" is also used by a licensed Avatar Master as a serious (dead)threat towards me.

“We warn you. Chances are great that we are going to discreate you, because we know your address! Idiot!”
