Dazed, punch-drunk; dizzy (with happiness)
I mean people are reluctant to go to ah ah public official. They feel you-know, (sarcastic voice) "He's the mayor," or "He's the council," or you-know? Ah I was slap-happy character. I'd invite everybody. So one day I had a guy come in and ah this- he was um- he was what they call displaced person- they used to call them D-P's way back but came over from Europe you-know after the war.
|The state where someone is sleep-deprived and everything makes them laugh. However, it seems like the speaker just uses it to mean an energetic happy person|
