Google is your friend when exposed 

Any NSman is still way above a fugging CECA DALIT like you!  Ptooi!

I don't need to Google.

Today they call it OCS but last taim the popular short form was OCT and we said SAFTI and not OCS.

Today they eat food nicely prepared by SATs Catering while last taim the army boys ate food cooked by you 

Today we say ORD but last taim we said ROD. 

I suppose these are things your mother couldn't teach you because Singaporean chabors didn't/don't have to do NS.
