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."
What you say so you won't look stupid in front of your crush, when you really did not know that.
Alisha asked what period they had next although this was the last period of the school day. She brushed it off with a, "Pssht, I knew that..." when her crush walked by.
Pushti is cool and very friendly to people that are close to her. Those who see her for the first timemay be afraid to approach her due to her poker face but, no worries just try and talk to her. Also she might be sarcastic most of the time but maybe it's her bizarre way to express herself. But do not mess with her and get on her dark side else, she will mess up your life.
