PFFFT!! 

PFFFT!! PFFFT The sound your lips pressed together and blowing air through them makes as you witness some idiot make a bigger fool of him or herself either by what they said, wrote, did. A show of utter disgust, no fear and the act of totally brushing someone off by dismissing them as a complete moron not worthy of one's time.

note: could be immediately followed by a brushing away with one's hand ending with a palm towards the buffoon.

(ex.) When you open the door to meet your blind date and a delusional 250 lb. water buffalo lied on her dating bio as being "just pleasingly plump." PFFFT!! Oh really? Maybe you should have listed your body type as "the Michelin Man."
