To call do-over

To desconsiderate, to neglect, to ignore something envolved at some circumstance. It can be used more often during kind of games or situations when a person does not want to count with the effect or the result of them.
The semantic of only "do-over" matches with "to restart", then do not mistake the meanings.

— Wait... you said I coudn't move the pawn like that.
— No, I didn't...
— Of course you did it!
— Whatever! We just need to call do-over
