Here are some possibilities:
* A playful or affectionate term for a friend or companion. It could be similar to "buddy" or "pal", but perhaps with a slightly more intimate connotation.
* A term referring to a romantic partner. However, this is highly speculative and without any context, it's impossible to confirm.
To get a more accurate definition, you need to provide more context, such as:
* Where did you hear the term? (e.g., in a book, a movie, a conversation)
* Who was using the term? (e.g., friends, family members, strangers)
* What was the situation? (e.g., a casual conversation, a serious discussion)
Once you provide more context, I can provide a more accurate and informed definition of "cuddy buddy".
