A Malaysian word which means worthless, if translated
literally.
It's a common expression used by locals when they crapped their pants, stressed, or missed something important. It's used the same way you say "shit!", when something goes wrong.
It's not overly offensive but it can be used as a minor insult when you feel
like someone's being a piece of shit, or they're just
dumb.
Example
1:
Me: *got kicked by my landlord*
"TAK GUNA!"
Example 2:
"
Hey Andy, I used your toothbrush to clean the stove this morning.
Hope you don't mind."
"Tak Guna you!!"
