When one is unsure if the abdominal pressure one is about to release will come out in gaseous form, solid form or some combination of the two, this is described as a 'risky fart', due to the certain degree of danger in the release (the risk that you might follow through).

Curries and other spicy foods are a prime cause of risky farts.
Whew, that was a great curry last night. It caused a few risky farts today though.
