When I was a kid we called it ‘knock down ginger’. No idea why. We would just knock and run. Lots of fun. Once or twice we were chased by grown ups. I don’t really hear of kids doing it today, probably because everyone has ring cameras or similar things nowadays.

I heard it as knock down ninja

Yall had fun names. Ours was just ding dong ditch.

The ginger bit was anti-Irish racism from the people who have literally committed genocide multiple times against the Irish.
