The act of ripping a rancid fart in a sleeping bag and holding it in all night, rendering any clothing involved completely saturated in a sulfurous odor. Thus, causing you to jump out of the sleeping bag in the morning, strip away your clothes, and air them out in a flapping motion, similar to the action of an emerging butterfly shedding its cocoon and drying out its wings in order to complete its transformation.
