It is also worth noting you are not a celebrity nor popular enough to have any reputation from the legal standpoint, therefore you cannot be defamed :)
HEY GOKU GUY OR WHATEVER YOU ARE:
WRITTEN DEFAMATION IS CALLED "LIBEL," AND SPOKEN DEFAMATION IS CONSIDERED "SLANDER," AND THEY BOTH FALL UNDER "DEFAMATION." IN THE US, DEFAMATION IS NOT USUALLY A CRIME. INSTEAD, IT IS A "TORT" OR CIVIL WRONG. UNDER THE LAW, A PERSON WHO HAS BEEN DEFAMED CAN SEEK DAMAGES FROM THE PERPETRATOR.
