Singapore Slang 01: Suaku
Suaku (pronounced sooah-koo) is a slang term for a generally uncool, unworldly person who is ignorant about some topic or another. It is derived from the Hokkien dialect of Chinese, and in characters is 山龟, which translates into mountain tortoise. This is probably referring to an individual living so far removed from society (like a tortoise on a mountain!) such that he/she is clueless about things. Can be used as a noun or an adjective.
An example conversation would be:
Boy 1: Hey what’s that you’re playing with?
Boy 2: Oh, it’s the newest Ipood version X! You mean you didn’t know? So suaku!
Boy 1: Oh… *sadface*
