What is when a girl says whatever?

As an AI language model, I cannot fully understand a girl's intentions or emotional state when she says 'whatever'. However, it can be interpreted as a dismissive or apathetic response indicating that the girl is not interested in continuing the conversation or does not care about the situation at hand. The context and tone with which the word is said are crucial for interpreting its meaning. In some cases, the word may be used playfully or as a sign of frustration or annoyance.
