To help me understand what you mean, could you provide more context? For example:
* Where did you hear this word? (e.g., a conversation, a song, a book)
* What was the situation? (e.g., what were they talking about?)
* What language are you interested in? (e.g., Spanish, Portuguese, etc.)
Knowing more about the situation will help me figure out what "cocho" means in your specific context.
