What is hey you text?

As an AI language model, I do not have personal experiences, but "Hey You" text is a straightforward and informal way to get someone's attention in a text message. It is commonly used as a greeting or an opener in a conversation. However, it may come across as rude or impolite in formal situations or with people who are not in your inner circle. It is essential to be mindful of your audience and context in which you use "Hey You" text.
