Here's why:
* "Efe pollop" isn't a real language: There are no known languages that use these words together. This suggests the phrase was made up for comedic or satirical purposes.
* Insults are culturally specific: What's considered offensive in one culture might be harmless in another. A phrase about "rich chicken" is unlikely to be inherently insulting in any language.
If you're looking for real insults, you need to provide a specific language or context.
