What is what does psh mean in text?

In text and online communication, "psh" is often used as an onomatopoeic expression to convey a dismissive or skeptical sound, similar to a scoff or a sarcastic exhalation. It can indicate disbelief, annoyance, or a lack of interest in response to something someone has said. For example, if someone made an outrageous claim, another person might respond with "psh" to show that they find the claim hard to believe or not worth taking seriously. The usage and interpretation can vary depending on context, but it generally carries a tone of casual dismissal.
