Referring to 53-year-old Smith's apology video released in July, Chris said, "F*** your hostage video".
The comic also used the set to refer to Will as "Suge Smith", in reference to the thuggish and imprisoned Death Row Records executive Suge Knight.
Rock told fans, who attended his and Dave's performance at Liverpool's M and S Arena, Will had managed to do an impersonation of a "perfect man for 30 years" before showing he is "just as ugly as the rest of us".
This is the first time the comic had extensively shared his feelings about being slapped by Will at this year's Oscars.
Dave asked Chris in front of the crowd, "Did that s**t hurt?" prompting Chris to exclaim, "Goddam right... the motherf**ker hit me over a bulls**t joke - the nicest joke I ever told."
He added, "Will did the impression of a perfect person for 30 years, and he ripped his mask off and showed us he was as ugly as the rest of us. Whatever the consequences are... I hope he doesn't put his mask back on again, and lets his real face breathe. I see myself in both men." (IANS)
