What is what does catching feelings mean?

Catching feelings is a slang term used to describe the act of developing romantic or emotional attachment towards someone. It is an expression of the moment when a person realizes that they are no longer just physically attracted to someone, but they have started to develop more profound and emotional connections with them. The term is often used in the context of casual dating or a hookup culture, where one may try to avoid getting too emotionally invested in someone, but ends up doing so unintentionally.
