The incident happened last Sunday evening as Rock made a joke about Jada Pinkett Smith's alopecia, causing a furious reaction from Smith.
The actor stood up, walked on stage and slapped Rock, before returning to his seat and shouting at him. Now, that moment has become a popular tattoo.
In Italy, artist Giovanni Bracciodieta posted a picture of another tattoo of the moment on Instagram alongside an anti-violence message.
