Pissshh

A quietly dismissive sound that is vocalized when completely brushing aside another's ideas or comments. This noise is also used to reject or blow off someone in general, possibly based solely on their physical appearance or behavior. When on the receiving end of this, one will feel like a complete, idiotic ass. There's no effective comeback to retort back for the one who's been addressed with this, however the giver will immediately have a wave of superiority rush over their entire body.
