What is is hi there flirty?

The phrase "hi there" is a casual and friendly greeting. Whether or not it is considered flirty depends largely on the context, the relationship between the people involved, and any accompanying body language or tone of voice. If someone uses "hi there" with a certain tone or follows it up with playful or teasing language, it might be perceived as flirty. However, on its own, "hi there" is generally a neutral, informal way to say hello.
