What did McMurphy respond to the doctor when asked if he was crazy?

From the text:

“Right here, Doc. The nurse left this part out while she was summarizing my record. Where it says, ‘Mr. McMurphy has evidenced repeated’—I just want to make sure I’m understood completely, Doc—‘repeated outbreaks of passion that suggest the possible diagnosis of psychopath.’ He told me that’psychopath’ means I fight and fuh—pardon me, ladies—means I am he put it overzealous in my sexual relations. Doctor, is that real serious?”
