Kachika
A stupid word you scream when you're so happy you think you're going to die. You can say it twice if it was extra stupid.
Kachika! I got an A+ on my math test and my dog did a dance!
Kachika, Kachika! My mom let me eat cereal for dinner.
Kachika! My brother fell into a mud pit and it was the best thing ever.
