Dad spanks teenage girl's not-so-teenage boyfriend

There are many strange, surreal aspects of a YouTube video purporting to show an angry man spanking his daughter's boyfriend for having sex with her (and why was it taped?). Let's unpack: the boyfriend is "about 27" and the girl is 16, according to the girl's older brother, who said he uploaded the video. The man doing the (bared ass) spanking is the girl's father. He gives the boyfriend an ultimatum of a "severe ass kicking" or "brutal spanking," the latter of which he also gave his daughter (think about that one for a minute). After the spanking, the dad tells the boyfriend to "consider himself lucky" because he could have had "rape charges plus an ass kicking."
