It was briefly a massive craze back then and I had no idea that POG meant anything apart from bottle caps. When Californian and Hawaiian friends introduced me to POG, the juice drink (which is freakin’ delicious) I was tickled.
It’s very easy to make yourself if you’re not on the West Coast. Just go to any supermarket with a decent Goya section and get bottles of the passionfruit and guava nectars and mix them with orange juice. Maybe add some pineapple juice if you want it extra-tropical.
