Is "crease up a paper" an idiomatically correct expression for the action of taking a piece of paper in your hands and pressing it into a ball? The action you would do, for example, if rejecting something you have written on a paper, before throwing it into the trash can.
Are there other idiomatic expressions for the same thing, and when would they be used? Is there a word for the result of this action – the "ball" of paper?
Edit: The title now reflects the correct expression.
