Thanks for the clarification.

It could be 10+ years of me misremembering the explanation. The person who told me this was Korean, so it seems more likely that I misremembered than them explaining it wrong.

Someone told me that Oppa means ‘Uncle’, but in the particular district of Gangnam the word Oppa/Uncle also means Pimp.

So it’s basically a song based on a pretty bad pun. I’ll protect you like an uncle, and by Uncle I mean Pimp.

EDIT: English speakers likely would do better with the translation as 'Ill be like a Father to you, a real Las Vegas Pimp Daddy (where Daddy is a word that means Father but has more Pimp connotations, and Las Vegas being famous for legalized prostitution).

It’s definitely debauchery. But we likely have memorials to Austin Powers and other such pop culture icons, so it’s understandable.
