Slapping a person in front of a crowd: SLANDER by deed
Slander by deed is a libel committed by actions rather than words. The most common examples are slapping someone or spitting on his/her face in front of the public market, in full view of a crowd, thus casting dishonor, discredit, and contempt upon the person of another.
