Meaning
Expressing that something cannot happen.
Cultural Background
In Java, saying 'Tidak mungkin' directly to an elder is considered 'kasar' (rough). People often use 'Mboten mungkin' (in Javanese) or soften it with 'Sepertinya' (It seems). Jakartans are very direct and use 'Gak mungkin' or 'Gak mungkin banget' (Totally impossible) constantly as a filler for any surprise. In Indonesian business, 'Tidak mungkin' is often replaced by 'Kami akan usahakan' (We will try) even if they know it's impossible, to avoid saying 'No'. Many Indonesians believe that 'Nothing is impossible for God,' so they might follow 'Tidak mungkin' with 'Kecuali kalau sudah takdir' (Unless it's fate).
Use 'Gak' for instant fluency
In 90% of conversations, say 'Gak mungkin' instead of 'Tidak mungkin' to sound like a local.
Watch your tone
Saying 'Tidak mungkin' with a flat tone can sound rude. Use a rising intonation to show surprise.
