"Ngeteh" derives from the word "teh" - tea, and the prefix "-nge" would define the word as drinking tea leisurely while chatting away. So it doesn't really matter whether you are having other type of beverage, it is still "ngeteh".
This happened like two nights ago when suddenly Arif called me up for a ngeteh session. This should be done earlier but due to his tight schedule, finally we had the chance to see each other since a time long ago I couldn't even remember.
So thanks Arif. Next time, we should sit and talk longer. There are too many things to update.
