Bagus: pronounced as bagos or baɡʊs
Meaning: good, wonderful, fine, alluring, useful, enjoyable, pleasant taste, well done (congratulatory), great work done, etc
But here in Malaysia, there is another meaning....
Mom/Dad: Son, don't run or you'll fall
Kid: *runs anyway*
Kid falls, blood on their shin and cries
Mom/Dad: Ha! Bagus! Bagus! Runa again la! Bagus!
In this example, the parent was not encouraging the Kid nor congratulate them on their action. It's almost a sarcastic remark and has the opposite meaning as in, "Great work, Kid, do it again and hee how much more painful when you fall again".
In other words, "I told you so"
