What is what does psh mean in texting?

In texting, "psh" is often used as an onomatopoeic expression to convey a sense of dismissiveness, disbelief, or slight annoyance. It mimics the sound of someone exhaling sharply or scoffing. For example, if someone says something that you find exaggerated or unworthy of concern, you might respond with "psh" to indicate your skepticism or disregard. It’s a casual, informal way to express those emotions in written form.
