Here's why it might be incorrect:
* Pronunciation: Lakota has specific pronunciation rules, and "shoomanee" and "owachee" don't seem to follow them.
* Meaning: The individual words "shoomanee" and "owachee" don't exist in Lakota vocabulary.
To help you find the correct meaning, please provide more context:
* Where did you hear or read this phrase?
* What was the situation surrounding it?
* Can you remember any other words from the sentence or conversation?
