SORI cup is an idea often used by youthful Papua New Guineans when meeting together to share a few substances based on alcohol.
If I am accurate, many young people in Papua New Guinea today are alcoholically savvy.
A large number of alcoholic substances are not factory made but, manmade: yawa, white soup, ombru and steam are among many choices. Probably not names familiar to you.
They’re concocted either by people producing for their own consumption or by others looking to earn some easy money.
