Zok!
ʔisíi timíipn’ise ʔúuc’uc háama?
“Who remembers Batman?”
Onomatopoeia in action!

Nez Perce has wide range of sound symbolic expressions or onomatopoeia. Growing up, I always remember hearing the expression “púk’!” whenever I or someone was observed to hit their head. In it’s original meaning it is the sound of Coyote dropping dead.
The above zok! would be t’ak’! in Nez Perce meaning the sound or manner of dealing a blow.
