Kablambo
Kablambo is when your brain short-circuits because the surprise was way too loud.
I was sitting in class. Kablambo. My teacher announced a pop quiz and my friend started singing in the back.
I was eating my lunch. Kablambo. My little brother spilled ketchup on my shirt and my dog stole my sandwich.
I was about to go to bed. Kablambo. My mom said I had to do my homework and my dad came home with a pizza.
