Kachonka - It’s the word you use when you don’t want to admit you messe

It’s the word you use when you don’t want to admit you messed up. It’s like saying ‘I didn’t do anything’ when you clearly did.

I didn’t fail the test. Kachonka.

I didn’t forget your birthday. Kachonka.

I didn’t eat your lunch. Kachonka.
