I SAID!!!!

I'm doing zig zags Mum!!!!!

Ahhh, the sweet words of Nikita in a huff. I only asked her to hurry up & finish off her bikkies. She was having some rice crackers for afternoon tea, and doing a jigsaw puzzle at the same time. I asked her once to hurry up & she said she was doing zig zags. 10 minutes later & I asked her to hurry up again & she yelled the above at me.

Can anyone decipher the meaning of her response?
