A sound generally used to convey annoyance.

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed

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

It is most commonly used when a person is annoyed or disagrees but can be used to agree and insult and whatnot.

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."

used to interrupt. kinda like "shut-up". usually used with the "hand in the face".
