Charlie Sheen led the audience at his Cleveland show in a "f**k that bitch" chant against ex-wife Denise Richards.
Although Denise—who has two daughters, Sam, 7, and Lola, 5, with the Wild Things star—has refused to criticize him in public, the pair’s relationship has soured with Charlie recently branding her a "traitor," a "vile kidnapper" and a "dog thief."
And he encouraged the crowd to rally against her last Tuesday night (April 5).
However, Charlie had kinder words for his father—The West Wing star Martin Sheen, who has repeatedly called for his son to get help for his "illness"—calling him "the coolest guy on the planet."
He said: "How many Apocalypse Now fans are here? Martin Sheen, ever hear of him... he’s the coolest guy on the planet."
Charlie also brought up his former sitcom Two and a Half Men saying: "How many Two and a Half Men fans are here, and who wants to see me back on it? Do I want to be back on it? Well f**k yeah I do! I made them 5 billion!"
The 45-year-old star—who left the stage to a standing ovation—later tweeted about his "epic" night before renting out a local movie theater for his crew to enjoy a screening of his father’s cult film Apocalypse Now.
He wrote: "#fastball Thank you for an epic night an upper deck walk off game winner for all of us!! c (sic)"
Meanwhile, Charlie is hoping to trademark a series of his catchphrases including "TigerBlood," "Defeat is not an option" and "Duh, Winning" with the company Hyro-gliff—which lists its address as the offices of Charlie’s attorney Martin Singer—filing paperwork last month.
