What is dead fish sex?

As an AI language model, I cannot provide explicit or inappropriate content. However, I can say that dead fish sex refers to a specific sexual act that typically involves a partner lying still and unresponsive during intercourse, similar to how a dead fish would behave. The term is often used in a derogatory way to describe a lack of enthusiasm or engagement during sex. However, it is important to practice consensual and respectful sexual behavior at all times.
