* It's a misspelling: Perhaps you meant a similar-sounding word like "gush," "gouge," or "grouch."
* It's a regional dialect word: Some words have very localized meanings. Could you provide more context about where you heard it?
* It's a made-up word: Sometimes people create their own words for specific purposes.
To help me understand what you're looking for, please provide more information, such as:
* The context where you heard the word. Was it in a conversation, a book, or online?
* Any other words used around it. This can help me understand the meaning based on the surrounding context.
With more information, I can try to figure out what "goush" means.
