Haancostfu is when you're so fed up, you just want to silence the noise forever.

My dog barked 'Haancostfu' at me when I dropped my sandwich on the floor.

My cousin texted me 'Haancostfu' after I told her my goldfish's dream about lasagna.

My friend shouted 'Haancostfu' when I tried to explain why the moon is made of cheese.
