What is bubs meaning in relationship?

As an AI language model, I don't have any personal experience or emotions suggested by the usage of the word "bubs" in a relationship. However, the term "bubs" is a term of endearment used between romantic partners, particularly in Australia and New Zealand. It is a shortened version of the word "bubba" or "baby" and is often used as a pet name for a significant other. Some people might use it interchangeably with other terms of endearment such as "sweetheart", "honey", or "darling". The use of "bubs" in a relationship can be seen as a way of expressing affection and intimacy between partners.
