Get to Know Your Farts 15

The Silent but Deadly (SBD) Fart:
The type that remains totally inaudible, yet somehow causes all the occupants of a room to collapse. Can smell like anything, nasal investigators rarely have time to distinguish an odor.

The Sphinctal Napalm:
Tends to happen a few hours after eating hot curry. Never mind the smell, worry about the burning sensation and the nasty stain it will leave behind.

The Squeaky Fart:
Sounds like 'Wheeek'. Normally smells foul.

The Stalker Fart:
Occurs when you leave the room to politely fart somewhere else, to save people the trouble of breathing in your flatulent demon breath. You go back into the room, but Yowza! The foul nose bomb has followed you, and you are lectured for your disgusting manners.
