The first thing the picture made me think of was that OK white power symbol racist bigoted fucks use.
Edit: I stand by what I said but also because I don’t know things and learn them everyday:
While it's true that some Filipinos use this gesture to mean 'okay,' Filipinos more commonly use it to mean 'money,' or 'pera,' 'kwarta,' 'datung,' 'anda' (slang words for 'money').
That’s all for today’s Dumb American Learns About Other Cultures!
