A small release of flatulence or gas from the rectum which usually is silent or close to silent. Usually the owner will try to contain a "ripping fart" and embarrasment in a public place by pushing the gas out slowly, thus causing a *puff* of noxious poison. Most often the owner of the puff fart will grin mischievously and whisper to himself, "That was silent but deadly".
Jane and Frank were out on a first date in Frank's new BMW when Jane felt a gas attack come on. She tried to hold it in until they got to the bar, but she had to lift her right cheek and let out a small but stinky puff fart.
