Pssht is a greeting.

All you have to do is stick out your thumb, index, and pinky fingers and say, "Pssht!" whenever you see your friends.

You can do a behind-the-back pssht or an under-the-leg pssht, etc.

You can say it really long, like "Pssssssssshhhhhhht," usually by adding more s's and h's.

The pssht is kind of like Spiderman -- oh wait, except NOT! Notice how Spiderman doesn't use his thumbs, his webs come out of his wrist not his fingers, AND he doesn't say "Pssht."
"Pssht" said Josh while psshting.

It can mean whatever you want as it is used in many situations.
