Get to Know Your Farts 18

The Windy Fart:
The sort of fart, which goes 'Whoosh', and is more felt than heard. A little like an SBD, but a bit louder and not so toxic.

The Worrying Fart:
The kind that seems to be a fart right up to the point at which you release it. At this stage matters become less sure, as it feels too solid for comfort. You go to the bathroom and check your underpants at the next possible opportunity.
