That's the only thing I see crazy here. (Calling your father "daddy" is also crazy but I digress).
People joke differently in each family. Once I was looking crazy at a friend and his family cursing at each other specifically younger members cursing around and to elders, but it was normal for them. I talked to my grandmother in front of them and she told me to be safe with the girls out there and I replied "You know I have condoms on deck. I'm not gonna make you a great grand just yet" and their whole cursing ass family looked at me like I just said Hail Satan.
