An act that is immature, self centered with a lack of empathy, emotionally fragile, avoidant, bears grudges secretly but acts chill, give up easily. Basically an abhorrent behavior with no sense of remorse or responsibility or effort.

A combination of two words in two different languages. Sian, in hokkien, means bored. Bodoh, in Malay, means stupid. While the combination of these two words makes no sense whatsoever, it is widely believed that this term was coined to build rapport with the Malays.
*In a classroom scene*

K.O: eh sian bodoh!
Jack: why are you speaking like a damn malay?
K.O: so that I can establish some sort of a bond with the malays
Jack: AAahahahahahah
Teacher: aaAAAHAHAHAHHA
Class: AAHAhhahahahaa
Malays: what's so funny?
