Aku Sumatra

Aku Sumatra literally translated to I'm Sumatra, Sumatra being the name of Indonesian Western Island, most people didn't know this so when you mention this people will ask what is Aku Sumatra and you can then talk about that for added topic in your conversation.

Use this when you ran out of topic when speaking with someone.

E.g

A: This is getting awkward. .

B: Aku Sumatra

Using that will spark another conversation or atleast new topic to continue your conversation
