Volcanal 

A volcanal is when you suddenly develop an uncontrollable bout of hot bubbly farts. This is usually the result of eating hot spicy food. They aren't loud but they stink to high heaven. It is pronounced volkaynal.

I was so embarrassed the other day. I was standing in a queue when I developed a volcanal. Everybody was looking at each other wondering who it was.
