When there is a hookah, or other smoking object, going around a room and someone is sitting in the circle and forgot to wear a belt. When another member of the group notices that they have half of the ass hanging out of their pants the member proceeds to blow the smoke down their friendspants. Therefore creating smokey mountains.

A man lights his partners pubeson fire and stomps them out. then, he places his genitals into her mouths and begins moving back and forth vigorously while lighting small patches of her hair on fire and punching them out.
