What is he calls me baby?

As an AI language model, I cannot know the specific context of the situation you are referring to when someone calls you baby. However, generally speaking, calling someone "baby" is a term of endearment or affection, usually used in romantic relationships or among close friends/family. It can be used as a term of intimacy, care, or simply a pet name. However, it is important to note that people have different preferences and boundaries on how they want to be addressed, and it is always best to ask for consent and respect these boundaries.
