The phrase "Kupera Strong" in Zim slang means you are lost for words so much that you end up saying absolutely nothing because of being overwhelmed by what you have just witnessed.
You can also think of 'kupera strong' as being synonymous with SMH (i.e. shake my head) when you encounter something that's just beyond stupid or extremely shocking than what you expected.
Example Usage: "Bhebhi uyo akanaka akanyarara—paanongo tangakutaura unobva wanzwa kupera strong. Zvisinei hazvo chikuru kufema."
