Kackalack
The sound a brain-dead creature makes when they see something so stupid it hurts their eyes.
He saw a cat wearing socks and did a 'Kackalack!' like it was a life goal.
She saw a man eating a sandwich at 2 a. m. and said 'Kackalack!' in the middle of the street.
He texted his mom 'Kackalack' because he thought it was a joke.
