It's when you put your balls in a girls mouth, put your asshole over her nose, and then fart.

ĭ-rā'nē-ən găs măsk

The act of placing your balls over a person's nose with the intent to restrict their breathing (thus forcing their mouth to open), then farting into their open mouth.

May be used on either sex. Do note however, that in most cultures, "no homo" must be called if performing the Iranian Gas Mask on men.
