Hachinpa
Hachinpa is when you call someone a fake, lying, piece of garbage because they said something you don’t believe. It’s like saying 100 percent, but with extra attitude.
Your dad: Hachinpa? I didn’t eat your mom’s cake.
Your friend: Hachinpa? I didn’t even know your mom had a cake.
Your sister: Hachinpa? I didn’t eat your mom’s cake or your dad’s sandwich.
