Hey you! Grrrrr.
Example usage of fierce face... One afternoon, the maid left the room while SE was having her nap. SE woke up, walked down the stairs and confronted the kakak:
SE: *fierce face* Why you leave little girl alone up-tair (upstairs)??
Kakak: ..... *speechless
At nights again wanting me to wait for her while she brushes her teeth with kakak, I prefer going off to brush teeth with JE instead. So I get confronted by this fierce face:
SE: *fierce face* Mummy, why you don't want to wait for me?
Me: (Inspired reply, or so I thought) I wait for you here
SE: No! You not waiting for me. You juh bruh (just brush) YOUR teeth
Hehe no escaping her wrath!
Don't play-play. I very fierce one
Me: No, this is mine
SE: *fierce face* Give me your water, I say!
(Of course she wasn't getting it like that!)
