Is it normal for your dad to smack your ass?

Tl;dr is it normal for his generation? (50)
Obviously, it’s somewhat normal to smack your kid when they do something wrong, but I mean just out of nowhere. Not hard, but like low key the same way I’d smack a girl’s ass at the gay bar. He hasn’t done it since I was like 13, because that’s when I discovered hentai and bdsm and all that shit, so I asked him not to. Anyways, he still sometimes says, “Come here, so I can give you a whippin’.” Then I say, “That’s weird, Dad. That’s like my girlfriend’s job.” He doesn’t touch my ass he just says, “TMI” or “You’re weird.”
