anda bernasib baik, nasib anda baik

used to say that someone is having good luck

:
You found a twenty-dollar bill on the street? Your luck is in!
Anda jumpa wang dua puluh dolar di jalan? Anda bernasib baik!
If you get the last piece of cake, then your luck is in.
Jika anda mendapat kepingan kek terakhir, maka anda bernasib baik.
