people are always saying that and it makes no sense, i think that you should say sign an affidavit or file charges someone explain to me how to press a charge
Press a charge, press charges, means to sign a complaint so the individual can be arrested.
If you think you are the victim of a criminal offense you do this: Go to the police and make a report. Write out and sign a sworn statement or complaint. The police will investigate and speak with the state attorney. If Probable Cause exists, they offender will be arrested or an Arrest Warrant will be issued for them. Once arrested, the state attorney will file a formal charge called an Information. The person will then be arraigned and scheduled for trial. Prior to trial, the offender will be offered plea deals. They either take it or go to trial. At trial, they are either found guilty or not guilty. If found guilty the judge will sentence them according to sentencing guidelines in your state for the crime committed.
