Yeah, birthday spanks are a thing in America, though it varies from family to family. People don't generally go for the total age amount though, usually just one playful spank from each person is enough.
Thanks for updating with English subs!!!! I honestly don’t know if it’s American culture or if Peniel is just teasing Eunkwang.... I’ve never heard of that before. What we’d do is just clap our hands with the age of the person but not to slap the person HAHA
The birthday punches thing almost seems like it's specific to certain cultures in the US. Like Samoa has it, but I don't know if we got it from years of western colonisation and also mixing with other cultures (a lot of Asian intermingling in the South Pacific Over the years). And so my white friends in the US Inland Northwest say they don't know of such a custom when I brought it up.
