When you and your friends are smoking some weed, and you can't get the lighter to light, because of wind, or whatever it may be. You tell them. Gather around the campfire, and they cover the flame with the hands.
The act of stuffing a marshmallow up youre bosses asshole, and then proceeding to fuck the marshmallow deeply inside him, like one was loading an old civil war musket. Then upon finishing inside said asshole, you both ride the slip n slide ithen ask him to evacuate the contents upon two eagerly waiting graham crackers. It is considered rude if the cracker is not consumed afterwards.
