Fiss 

A weak, barely audible fart of weak smell potency usually generated by petite women. Hard to detect because it is not accompanied by the moustache-hair-burning odor common to most recognizable farts. Low on Scoville Scale Heat Units, SHU's.

Karen, did you just fiss or was that a hiss coming from the jukebox?

Fiss 

A farty piss.

When one farts whilst going for a wee.

Oh mate. I was at the public toilet the other day- this guy came to piss next to me. By his expression you could tell he was having a Fiss.
