This is the most important part in learning new language. I know this is too early but honestly, who cares? Ok let's start now.

jungkook =

busuk =

baboon =

satan = satang

mangkuk = crazy / insane

biguk = stupid (in mean manner)

kepala lemak = stupid (in joking manner)

taekkembeng =

dez = d (you know)

vez = v (you know)

taekkau = cow's

That's all for now. I will update if there are more bad words. I hope it help you.
