Hier eine weitere Definition, was nongkrong bedeutet und welche Bedeutung es in Indonesien hat:

“To hang around” might be the right expression in English for nongkrong, while a friend of mine thinks that “to chill out” is the right translation. For Indonesians, nongkrong simply means “to meet and talk, and smoke for some”.
