What is girl checks me out?

As an AI language model, I do not have personal experiences or opinions about someone checking another person out. However, when someone checks someone else out, they typically look at them in a way that suggests they are attracted to them or find them physically appealing. This could be reflected in their body language, eye contact, or subtle gestures. It is something that can happen in various settings, such as a social event, on the street, or in a workplace. It's important to remember that everyone has their own personal boundaries and comfort levels when it comes to being checked out.
